After being late to science class, Max settles down next to Liz and slips her a note. She drops her pencil intentionally, and he slides under the lab desk to caress her hand.

His touch prompts another vision for Liz: a dark star in a spiral galaxy. She moans, which attracts the teacher's attention and wins Liz and Max detention.

They slip off to a storage area to make sure. As they kiss, Maria tells Michael that she has seen visions: stars flying by and "and incredible sunset, like near the rings of Saturn."

He shares a vision, too: a young Maria trying to tie the laces of her red sneakers.

Liz and Max kiss passionately in the Eraser Room. He sees a vision of her playing dress-up as a child, but pretends he saw nothing when she asks.

The two resume kissing, and this time Liz sees stars, Jupiter and then the Earth. The final images are of something coming over the desert mountains.

Then the door opens.

Soon after, the principal explains the Eraser Room to Mrs. Evans and Mrs. Parker. This also requires explaining to Mrs. Evans that what Liz and Max were doing didn't involve erasers.

The principal and both mothers then join Max and Liz, who is mortified. She is further embarrassed by having to explain to her mother that she can't come straight home after school because she has detention.

Then he offers himself to her "in the interests of science" for experimentation with kissing.

"Not gonna happen, Alex," she tells him. He's not surprised.

In detention, Liz sees an astronomy poster which reminds her of what she saw in her vision. She asks the teacher to identify the formation, the Whirlwind Galaxy, and wonders if a red star might be there.

It could be a red giant, he tells her, whose light might not be picked up on Earth. After he leaves, Liz tells Max that she thinks that her visions might be of the crash itself.

Mrs. Parker interrupts Liz's studies. Liz does not want to talk about sex, but Mrs. Parker insists.

Her advice is simple: "Don't ever have sex. Don't ever leave this house. Don't ever stop being my baby girl."

While she may want Liz to remain her "baby girl," Mrs. Parker recognizes the changes in her daughter's life. Whatever happens, Mrs. Parker wants Liz never to lie to her.

At Michael's new place, Isabel puts groceries away as the three aliens talk. Michael seems to want to know more about what Liz saw, hoping that she saw their parents.

Isabel quips, "Yeah, Captain Kirk and the Klingons." She is more than skeptical.

Max admits that he has seen visions from Liz -- he thinks they're real, but hasn't asked. Michael pushes him to ask.

Michael soon returns to his own avenues of investigation. As he and Maria enjoy another make-out session, she feels compelled to admit that she's not "completely sure I've actually really had" visions.

OK, she further admits, she faked them.

As Michael -- clearly upset -- begins to leave, Maria stops him and suggests that the reason she can't see visions is because he is so defensive. He tells her that he lied about his vision, too.

As Liz and Maria prepare for gym class, Maria notices something and forcefully tells her to go look in a mirror. She begins to, but is interrupted when Max enters the girls' locker room.

Max explains, "I just had to know if something was real." Liz knows immediately that he is referring to her fantasy.

Max had wondered if the fantasy was just his own imagination, but he's never seen the girls' locker room until now. He also tells Liz that he knows how she felt in her fantasy, and that nobody's ever felt that way about him before.

The gym teacher returns looking for Liz, and the two teens hide in the shower. He looks to her neck and sees what Maria saw -- a glowing hickey.

Max puts his hand on the hickey, causing Liz to see another vision. Soldiers leave a US Army jeep. Someone breathes hard, hiding in the desert brush. The soldiers fan out, running with guns.

Michael and Isabel speculate about the visions at his place: is this is how their people remember? Are they messages from Nacedo, the fourth alien?

Max enters, telling the others that Liz is on her way. Max is uncomfortable at the thought of using her.

Michael encourages Max, saying that he must do this for their mutual good. Besides, getting closer to Liz is something that Max wants to do anyway.

As Michael and Isabel leave, she turns off the lights and snaps her fingers, lighting candles all around the room. Liz arrives while Michael is admiring Isabel's work, and the two make an awkward exit.

Liz is initially upset that the others know, but she wants to understand what is going on. Max places his palm over her hickey, and it disappears.

She tells him to remove his shirt and helps him to do so. Running her fingers over her chest, she remarks how she is unable to have the same effect on him.

"I'm glowing everywhere," he tells her. "My toes. My heart. You can't see it -- it's on the inside."

For a moment, Liz has doubts about their relationship, and wonders if she can get sick from him. On the other hand, she speculates, perhaps the mark was caused by lack of physical intimacy.

The two pull closer together, kissing more and more passionately. Liz tells him, between kisses, "My mother who I love, is gonna kill me. If I don't die from this."

A moment later, Liz tells him, "I can't stop."

As the two lie down, she hears a beeping sound. She sees soldiers, a sign which reads "Restricted Area" and a tower labeled "Transmission Tower 31." Someone is burying something.

Then Maria bursts in, looking for Michael.

Maria drives her friend home, asking questions all the time. Maria is concerned for Liz's safety and doesn't want anything bad to happen.

Liz is not convinced, though, noting that Maria and Michael have done more than kiss, too. Maria points to Max's alien nature, though, and is unsure about what could happen physically.

When she arrives home, Liz jumps across the roof and prepares to open her window. Mrs. Parker is sitting on Liz's bed.

Mrs. Parker accuses Liz of thinking her stupid. Liz accuses her mother of being controlling.

Liz says that she wants the space to be her own person, even if that means not being the perfect daughter. Mrs. Parker is concerned about Liz's high temperature.

"This is my body, and I don't have to tell you every single thing about it," Liz screams before slamming her bathroom door.

Later on that night, as Liz writes in her diary, Max calls to her from outside. Neither of them can sleep.

Liz shows him a drawing of what she saw, which he recognizes as an old radio tower near Highway 42 -- a location near the crash site.

Even though Max initially wants to get Michael, Liz convinces him to let her come along instead. "All I know is if we're gonna do this, we've got to do it tonight," she tells him.

Getting out of the Jeep, Max wonders aloud what they should do next. Liz points out that they could start digging, or they could "look for the next clue" with more kissing. More kissing ensues.

He spreads a blanket out and asks if she is scared. She tells him, "Well I know I'm supposed to be, but I'm just going to put myself in your hands."

They are interrupted by a coyote cry, which startles Liz. As they kiss again, they hear the beeping sound which Liz recognizes from her vision.

They follow the sound and begin digging. A bright blue-white light breaks from the ground, shining into the night.

Max reaches in and pulls out a small gray ovoid, with a glowing symbol on it from the cave painting. Liz wonders if this is a signal.

In the early morning, Liz sleeps outside with Max's arm around her, fully clothed. The object sits on the blanket next to them. A shadow passes over them, lingering for a moment.

At the Parker home, Mrs. Parker opens her daughter's door to find the bed unslept in.

Isabel knocks on Alex's door and tells him Max and Liz are missing. He offers to lend his car for a search, but she asks him to kiss her, saying she hopes that this will allow them to find Max.

He agrees to do so, and after a moment but she relaxes into the kiss. After a few seconds pass, she pulls away and tells him, "Nothing. Nothing relevant to the current crisis."

As Isabel walks away, Alex calls out that she can feel free to try again in the future. Since her back is to him, only we can see the smile on her face.

Maria knocks on Michael's door, looking for Liz, but Michael cuts in, "I heard." She asks him not to be cold or mean to her, and he invites her in.

Maria admits that she fakes things a lot, but can't with Michael. She blames herself for the lack of visions, but he reassures her, telling her that she allowed him to see into herself.

He tells her more details about his vision with the red sneakers, and it is clear that this was a true vision. When Maria tells him that she just wanted to be closer to him, Michael puts his arms around her.

The Evans parents have gathered with the Parkers at the Crashdown Cafe. The fathers agree that their children have been exercising poor judgment.

Mrs. Parker wonders if the children should see each other. When Mr. Parker suggests the kids be allowed to explain, Mrs. Evans wonders what kind of explanation will suffice.

Back in town, Liz and Max are moving from the Jeep to the Crashdown. They kiss, but there are no flashes.

She asks, "So what you're saying is that you saved me from a life of watching Kyle barf?"

When pushed to comment on what he sees of her destiny, he tells her that he only knows "the part I'm hoping for."

The two walk hand-in-hand into the Crashdown Cafe to face their parents.
