Kate is rocking her "sweet girl," but she's rudely interrupted by aliens who take her baby away. She's in a cleverly crafted baby room inside the alien ship. She screams, please, let me remember this time. Let me remember!

OMG. What a tragedy.

Dan wonders what the hell Harry was thinking by allowing Asta to do recon with an alien. Harry can't remember much on an empty stomach, and Dan says that's his problem; he doesn't think of anyone but himself.

Harry disagrees. Others will want pancakes, too. He's wearing a shirt and shoes. Where is his service?

Asta reminds Dan that she chose to go on the date. D'Arcy says it was OK. She had Asta's back.

Internally, Harry wonders what the big deal is since all beings must fight to survive. Humans forget that they are surrounded by forces greater than themselves and that survival isn't guaranteed.

But he's got to go, taking his empty stomach to listen to Ben whine about his antidepressants ruining his sex drive. When Asta says Ben canceled his appointment to go to Yellowstone, Harry darts off.

Mike and Liv got nothing from fingerprints, so they begin looking at what evidence they do have, the photo included.

What Mike takes away from the photo is they are looking at a killer mime. Liv, more pragmatically, suggests the military. But there are no mimes in the military, Mike reminds her. Don't ask, don't tell.

Liv suggests they talk with Detective Torres, which makes Mike think she's trying to get them back together. She makes the call with lots of innuendo.

When they exit the office, Judy is all over Mike like a cheap suit. Oh, dear God, Liv says. Judy has brought along her mom, April. Her mom is only 14 years older than she is, so everyone thinks they're sisters. Judy invites Mike to her birthday dinner, where April says they'll talk about her dowry.

As the Hawthornes prepare to leave for Yellowstone, they find Harry outside, alerting them that he'll be joining them on their family trip. He tells them his parents died the day they were to leave on their own family trip. Max interjects. Maybe they should bring a doctor on the trip, just in case.

They agree to let him go, and he screams shotgun while running to the car.

Max wonders why Harry came along, and Harry lies.

Kate asks about a hot-stone massage, only to discover that the therapist is stuck in the snow.

Kate's nightmares continue even in Yellowstone. She awakes to a crying baby, thinking it was coming from the room next door.

Judy is singing karaoke when Liv arrives at the bar to ask D'Arcy about the photo. D'Arcy recognizes Harry immediately and doesn't play it very well.

Judy talks with Liv and plays up being Mike's girl and how she worries about him on the job.

Jay asks Asta to go to a scare-a-thon movie day on Saturday, but Asta has to work a double shift. D'Arcy enters next. They've got a code red. Liv and Mike are after Harry!

If they subpoena Harry's phone, then they'll get Asta, so D'Arcy wants to destroy Asta's phone. Except they don't need the phone to access digital records.

Harry pounds on the adjoining hotel room door, and Ben tries to ignore him. He wants coffee. But the coffee is snowed in too. There is some in the lobby. Harry wants to join the family activity for the day because dead parents. When Max asks how they died, Harry flips him off.

Kate chooses snowshoeing, but Harry wants Ben's intuition to be his guide. They decide to do Old Faithful, but Harry isn't so sure. Ben doubles down.

Ben joins Asta and D'Arcy while they search Harry's cabin for the plaid shirt.

D'Arcy finds the plaid shirts, and since the photo was black and white, they decide to burn them all.

Harry is upset that Ben doesn't seem overly interested in Old Faithful. What does interest him is a hat for a 70-year-old gravel company. Sullivan Gravel is why the mayor was compelled to come here, as evidenced when he purchased a hat with the logo from a man's head.

Mike saw Liv's grandma, who moves kinda fast. Lena calls Liv, and when Liv says he farted earlier, Mike thinks he was talking about him. It was the dog.

The Patience Post writes front-page article about Liv and her alien interest, suggesting that she may be using tax dollars for any number of things.

Liv gives him Judy's kissy napkin, and Mike sticks up for Judy, who is nice in her own quirky way. He decides to deliver a message to her in person.

Asta and D'Arcy enjoy a roaring fire and hot chocolate. D'Arcy is very happy she knows about Harry so Asta doesn't have to do all this alone anymore.

Dan sees how much stuff Harry has taken from the diner. Asta wants to eliminate any evidence of the alien tracker, but Dan wants her to relax.

He talks with her about coming back from Vietnam and living in a state of crisis mode. Asta doesn't have to do that anymore, and he wonders what it might be like for her outside of that mode.

Good-looking people don't work at gravel companies, let alone at night when they can't be seen. Max hid in the backseat, so he's there to help or hinder Harry's investigation. Max notices how good-looking the people are. Harry says they're hybrids, and Max asks, are they electric?

Judy is so excited to see Mike, who takes her to the back to talk. He tells her he can't make it to her birthday dinner and let's her down easy, but it's not so easy, and Judy is gutted.

Judy is going to cancel her birthday party now. She feels so stupid. She just wanted it to be her turn.

Harry finds a portal inside the gravel office. A hybrid emerges, and he goes down when Max uses the taser on him. Somebody want an orange, he asks? Is that his catchphrase? It's not very good.

Harry sends Max back to the car and goes down in the hatch, which he also discovered. The gravel company hides a massive Grey operation, probably in operation for decades.

Ben gets some hot stones and wants to give her a massage. But he got a turtle and microwaved it. He blew it. He just wanted to give her a chance to get off her feet. Any trip is better than no trip. She hears another baby crying. She follows the sound, remembering saying please let me remember this time.

Kate finds an actual baby in another room and asks to hold it, please.

The Greys are storing a bunch of water underground, and he needs to figure out why. Harry remembers the raccoon and realizes that they're creating a massive bomb using Yellowstone's already volcanic activity to do it.

Liv's nana is walking down the street. She's kind of mean to Liv. She was even interviewed for it as the unnamed source. She called Liv a fantasist whose understanding of reality is circumspect at best. Then she equates Liv to the cheapest girl in the whorehouse, making Mike frown.

Although she hides it well, she bursts into tears, and Mike comforts her.

Harry reports to D'Arcy and Asta what he discovered. He will stop The Greys from destroying the earth.

Even if he stops The Greys from destroying the earth, it won't stop Yellowstone from doing what it's going to do, which scares Asta even more. Dan says just keep doing what you're doing -- the best you can.

When compared to the age of the planet Earth, a human life would only be 141 seconds long. Harry will do what he can to ensure that they get to live their best lives for as long as they can.

A portal opens in Harry's living room. A blue alien named Heather arrives with a file for Harry. She's from the galactic federation and is being served in breaking galactic law by not leaving the earth as he had promised The Greys. He is ordered to leave immediately.
