Kat is telling Del about how she didn’t listen to Elliot, who told her that you can’t change the past, but she didn’t listen and went back, which ended up being the reason for Colton’s car crash. Del leaves. Alice, who was listening in, goes to check on her mom and asks why she didn’t tell her about being there that night.
Alice, feeling emotional, heads back to the 70s right as the Watergate news was breaking. She immediately shows her hand and reveals she knows about the secret messages Colton left in the books.

Kat tries to jump back to the 1800s to convince Jacob to come home, but the pond doesn’t take her.
Del is talking to Sam and asks why he was hanging out with Casey Goodwin. He explains that Casey is a client. They showed up one day asking for legal advice. Casey called the other day and said they were in town and wanted to catch up. Del asks why someone so young would need legal advice, and he says, “You know I can’t answer that.”
Alice goes to Lingermore to work on the project with Max. She asks if they can work in the attic, and he says no one has been in there for decades. She replies, “Dope, let’s go.”
Jacob powwows with Susanna and Thomas, and she says she knows that Kat fights for those she loves. She encourages him to go back home and talk to her, but Cyrus shows up, and he’s not thrilled. Jacob goes and jumps in the pond to come home, but Thomas tries to jump in too, and it doesn’t work.
Alice looks in the secret door and finds an old cell phone and a bishop chess piece. Max is very confused and then gets irrationally mad at her when she brings up his grandma.
Alice then goes and tells Del the truth about who was in the road that night.
Nick is still in town and is pushing for everyone to come together for a karaoke night.
Alice shows Kat what she found, and Kat says she thinks Casey was squatting in the Lingmore house last year. Casey walks in and is like, “IT’S ME!” And it’s true. Kbye.
Del gets another mysterious letter saying they know the truth. Her friend says it’s probably Sam, the person you least suspect.
It’s time for karaoke. Nick signs Kat and Elliot up for karaoke, and Del ends up showing up. Kat gives her a big hug. They make up, and Del says she wants to jump in the pond to find Jacob, but he ends up walking in.

Alice jumps back to the 70s to watch Colton say goodbye to Del when she leaves at the end of summer. He tries to get her to stay, but she doesn’t want to. It’s easier to leave. Turns out he was going to propose. Womp womp.
Jacob goes to put on Colton’s record when he sees a picture of young Colton and says, “THAT GUY CAME TO THE FARM IN THE 1800S AND TOLD US WHAT TO PLANT!”
Kat tells Elliot that she needs some space and then immediately jumps in the pond and makes out with Thomas.
Alice gets back from the 70s and sees Casey. She asks Casey about the ring, and Casey says, “It’s a family ring.” Alice asks, “Goodwin family?” and Casey says, “No…” and then just starts running. Alice runs after them, and Casey jumps in the pond and doesn’t come back up.
