Tess persists – they must retrieve Nacedo. Failing that, he once told her that if anything happened, that she should go to the pod chamber in the alien ship.

Michael overrules her. They will not leave anyone behind anymore.

Max wishes he could go back to when things were simpler. Liz wishes that he had not saved her life and ruined his, but Max stops her, telling her that it was her face – not Tess' or anyone else's – which kept him alive in the White Room.

"Knowing you has made me human," he says. His destiny is her.

Max wakes to the sound of a vehicle driving by. He wakes Liz, and the two of them begin to run.

They see Max and Liz being chased by a government jeep. Valenti stops the car, and Michael gets out.

Michael raises his hand, gestures to the jeep, and a bright light surrounds everything. Smoke emerges from the jeep.

The sheriff looks on, shocked. Liz and Max take advantage of the confusion, jumping into the police cruiser, and Michael tells Valenti to drive away.

Michael claims not to know what he has done.

Back at the mine, Valenti seems to think that they will be safe here, but Michael is doubtful they will ever be safe again. Michael stomps into the mine in a huff, and Liz follows him.

Outside, Valenti demands that Max tell him what happened. He had no idea Michael – and now, he realizes, Isabel – were aliens too.

Max reminds Valenti that this is a matter of trust, and that their lives depend on him. Now that he’s entangled with them, though, Valenti wants to know everything.

Max tells him that they do not know where they are from, nor do they know why they are here. But their intentions are peaceful, not to hurt anyone and to stay alive themselves.

Valenti laughs to himself, noting that his father was right, after all. Max points out the elder Valenti would turn them in – what will he do?

In the mine, Michael talks with Tess and Isabel about what happened. He cannot explain what he did, or why.

Tess explains that this is his energy and is shaped by how he focuses it. Isabel asks why he needed to do this in front of Valenti.

Max enters the mine. He cautions them not to panic, and Isabel asks if they are to trust Valenti.

Tess pushes for a more isolationist stance: they should go to the chamber and leave the others. Michael agrees and says that they cannot expect to stay here forever.

The aliens will leave, and the humans can stay.

Maria disagrees, promising to follow Michael. Alex does the same with Isabel, although more quietly.

Max stops the discussion. Pierce won’t give up searching for him, he says, and they now know plenty about alien hunters themselves.

It’s time to fight back.

Valenti sits alone in his police cruiser, fingers his badge and then removes it completely. He listens to the radio as the deputies talk about him, not sure where he or the six teens are.

At the Valenti house, Kyle demands to know where his father is, but Agent Samuels will only says he is there to protect Kyle from harm.

Outside the Crashdown, Tess and Liz wait while Michael and Isabel catch the attention of Agent Bellow. Tess makes the distracted agent see Pierce, who tells Bellow to go to an abandoned gas station in Hondo, outside Roswell.

Back at the Valenti house, Agent Samuels sees a similar vision, but the spell is broken when Kyle asks whom he's talking with.

As the confused agent tries to answer that question, Max surprises him and knocks him out with a single punch. Max tells the bewildered Kyle it's not what he thinks.

Kyle wants to know where his father is. Max assures Kyle that the elder Valenti is safe.

Max pulls Samuels into a closet and then uses his powers to fuse the doorknob shut while Kyle looks away. Max urges Kyle to trust him – he should leave the agent alone and stay here, out of danger.

Kyle tells Max, "If anything happens to my father because of you, I swear to God, I will kill you myself."

After Max leaves, Kyle tries the closet door. He goes to his father's gun case and removes a revolver.

Sheriff Valenti finds Pierce – back in his deputy disguise – sitting in his chair. The two exchange threats and then negotiate.

Valenti knows the aliens' plan, but he is scared – he wants assurances that he, Kyle, and his father will be safe. They are to get pensions and government protection.

Pierce promises this, if Valenti will lead him to the aliens.

Valenti and Pierce watch as Liz and Isabel go upstairs in the UFO Center. Pierce cautions Valenti to "shoot to kill" once all the teens are there.

Valenti is worried about the civilians, but Pierce tells him, "there is always a price to pay."

The lights go out.

Max and Michael have guns drawn on Pierce and Valenti. They quickly tie the two men up.

Max looks disappointed with Valenti, saying, "I can't believe I trusted you." Michael takes Valenti away.

Alone with the sheriff, Michael says, "I always thought you were out to get us. And I'm glad I was wrong." He releases Valenti, who was in on the trap for Pierce.

Valenti promises help from the Attorney General's office, where he knows someone. Secret parts of the government must be exposed to scrutiny.

As Max holds Pierce in front of a projector, asking him the same questions Pierce asked in the White Room. He even promises an easy way to get information and a hard way.

Max wants to know where Nacedo is, but Pierce refuses to talk.

In the projection room, Isabel prepares to enter Pierce's mind. She is scared, though, since she has never been in a conscious and resisting mind before.

Max continues to ask Pierce questions about Nacedo, echoing the agent again by threatening to take him apart, piece by piece, while keeping him conscious enough to see.

Inside Pierce's mind, Isabel sees Nacedo's body in a body bag, zipped up and placed into a hazardous waste container. Pierce orders the body taken to Jefferts Air Strip, where a helicopter will come for them once the other aliens have been captured.

Isabel is visibly saddened that Nacedo is dead. Tess claims that he cannot die, though – that the aliens have the power to bring him back from the dead using the healing stones in River Dog’s possession.

Meanwhile, Michael asks Valenti about this friend of his with the Attorney General. When it is clear that Valenti is not straight with his facts, Michael asks if there really is someone.

Valenti admits that there isn't. Pierce is a killer, though, and Valenti plans to stop him.

Left alone for a moment, Pierce attempts to break free. He sees Kyle sneaking around the center and calls out to him as "Deputy Fisher."

Max has the sheriff, Pierce claims. He gets Kyle to untie him, takes the gun Kyle brought from home, and tells him to get to safety.

Pierce hides the gun behind his back and pretends to still be tied up. When Max, Michael, and Valenti walk by, Pierce draws the weapon and fires.

Valenti pushes Max and Michael down to the ground and returns fire, emptying his revolver into the exhibits around Pierce. As he tries to reload, Pierce takes aim.

Michael holds up his hand, using his powers to throw Pierce violently against the projection screen.

Valenti approaches, with his weapon still out.

He examines Pierce, who is dead. He also that the gun Pierce was using is his.

Horrorstruck, Valenti looks through the fallen exhibits. He finds his son among the debris, shot in the chest.

Valenti cries as he cradles his son's body. He calls out for help.

He begs Max, "Save my son, please."

Max places his hand on Kyle's wound, covering it, and heals Kyle. His hand glows, and the wound seals.

Kyle coughs, and Max looks drained.

A clueless Kyle asks, "What the hell just happened to me?"

Valenti holds his son, looks to Max with tears in his eyes, and offers unconditional support of Max and his friends. He asks for a moment with his son.

Michael walks away, looking upset. Max tries to comfort him – he didn't mean to kill Pierce.

But Michael corrects him: he did want Pierce dead, and it just happened.

"What kind of person does that make me?" Michael asks.

Michael shapes his idea into a contrast: where Michael kills, Max heals. One is good, and one is bad.

Maria rushes over. She wants to help, but Michael pushes her away.

He is not safe. He cannot control his powers, and he doesn't need her.

Maria angrily asks why he is always so eager to throw her away.

"Maybe because I love you too much," Michael says. "Good bye."

Alex tells Isabel that he knows that she needs to do what comes next alone. He hugs her and then releases her.

Reminding Max that they choose their destinies, Liz follows Max and the others.

In the desert, the aliens surprise the FBI guards and take the truck which holds Nacedo's body.

Nacedo's body rests on a rectangular slab, and the aliens hold River Dog's healing stones. As the stones glow yellow, the slab glows a bright blue.

Underneath, we can see Nacedo's skeleton, which is not human. His body shifts between forms, one of which resembles the classic "grey" alien.

Nacedo changes back to Ed Harding and wakes up.

Tess tells him that she knew he would not leave them. Nacedo assures them that they are not ready to be left alone.

Max wants to know how the orbs work, but Nacedo tells him, "It's not my job to show you. My only job is to keep you alive."

The others are not ready to know about the orbs. Nacedo tells them, "Set off those orbs and you have no idea who you may be leading straight to us."

If they want to use them, the aliens have the power to unlock the orbs. They will do so at their own risks, though, and it’s not his job to teach them how.

Noticing Nacedo's reference to jobs, Max infers that he is not their leader. Who is, then?

Nacedo turns to Max, just as the others look to him, too.

The only way that the aliens will be safe in Roswell is if the hunt is called off, Max tells them. He asks Nacedo to replace Pierce with the FBI's special branch.

Nacedo becomes Pierce, promising the others the resources of the FBI. As he leaves, Nacedo tells them, "You will be safe now."

Max and Michael each take an orb. The aliens all concentrate, causing the orbs to glow brightly, and beacon light flashes on the rock atop the cliff\.

An image of a woman forms in front of the aliens.

"If you are seeing me now, it means you are alive and well," she tells them. Her form is designed to be familiar to them.

"You have lived lives before," she continues. "You perished in the conflict that enslaves our planet, but your essence was duplicated, cloned, and mixed with human genetic material so that you might be recreated into human beings."

The woman describes the Max, Tess, Isabel and Michael: "the beloved leader of our people," "his young bride," the woman's daughter, and her betrothed, who was the leader's second-in-command.

But the teens are not quite alone. She tells them, "Our enemies have come to the Earth. You will know them only by the evil within."

Their mission is to gain strength so that they might return to their planet to defeat the enemies there.

Everyone is stunned.

"Max, you do have a destiny," Liz says. "You just heard it. I can't stand in the way of it."

She kisses him and then turns to leave

Max follows her, but Liz continues walking away. She turns back briefly, looks at him somberly, and then begins the long climb down the rockface.

Holding back the tears, she breaks into a run.

Michael holds Max back from following. "You've got to let her go," Michael says.

Elsewhere, we see pulses of light much like the beacon atop the rock. From farms and towns, cities and country, the lights blink-- each with their own blipping sound.

A ominous looking man holds a device with five lights in the middle, sections of a pentagon. The lights flash more and more quickly.

The man holds the device up and proclaims, "It has begun."

We see the aliens again and then to a shot of Earth . . . from space.
