In the Landry kitchen, Del noticed Kat in deep thought. Kat tells Del that she’s been thinking about Colton and assures Del that she shouldn’t hang on to the idea that Colton was cheating. But Del tells Kat that she remembers a strange woman weeping at his funeral. Kat tells her it wasn’t anyone important and excuses herself. Del goes to the kitchen drawer and pulls out the grief support group card that Kat gave her.
In her room, Alice hears Colton’s voice encouraging her to embrace her singing talent. At the Point, she asks Spencer about performing at the opening of the Roxy. Spencer is excited to hear that she’s up for it.

In the Landry kitchen, Brady tells Kat that Alice has signed up to perform at the Roxy. Kat and Brady are both proud of her. Brady wants to chat with Alice about the divorce but Alice says she’s fine and doesn’t need to have the talk.

Alice wants to know why her mom didn’t tell her sooner. She wanted to say goodbye to teen Kat because she is her best friend. She storms off.
Alice heads to the pond and when she emerges, she has not arrived in the year 2000. Instead, she’s gone back only months – some time before she and Kat arrived in Port Haven. She sneaks into the Landry house and spies Del talking to Rita. Rita is trying to convince Del to send the letter that she wrote to her daughter and granddaughter.

Brady interrupts them to say he’ll be at Alice’s concert and that he loves them both.
Inside the Landry barn, Alice is practicing with her guitar. Del appears and tells Alice her singing was beautiful. Alice admits that she’s scared to perform, but Del encourages her to “do the thing that scares you.” She wishes that Colton was around to hear his granddaughter sing.
At the Roxy, Kat approaches Elliot. She’s nervous about Alice’s performance, asking to hold his hand through it. They take their seats and await Alice’s performance.

In the Landry kitchen, Del asks Alice where she learned the song she performed. She tells her that Kat sang it to her when she was little and she always remembered it. Del tells them she went to the grief support group. Although the people were nice, it wasn’t for her. Del apologizes to Kat for not being there for her as she was lost in grief. She tells them that Alice and Kat have been her support group. Since they’ve come back into her life, they’ve filled her heart. Kat says she’s grateful that Del sent the letter, but Del still says she didn’t. Alice smiles, knowing it was she who sent the letter after finding it in the trash, all those months ago.
The Landry dog, Fynn walks in with a torn up baseball that he got from the pond. Del tells them Fynn can’t stay out the pond. Kat recognizes the baseball as the same one that Jacob had. Could Fynn have time traveled in the pond as well? Kat runs to grab the Landry Almanac in the living room, where she finds a message next to a torn out page and Jacob’s hand-drawn initials: “The explorer found a home, but he still looks to the stars when he feels lost.” She has a flashback of teen Kat and Jacob lying together, staring up at the star-strewn ceiling of his room. Young Jacob says, “Did you know explorers used the stars to lead them home when they got lost?” Kat stares at the words in disbelief.
