The next morning, Cate and Lux wait on the porch of the B&B for Grant. For hours. Eventually the innkeeper delivers a message to Cate that "something came up last minute," and Cate has to acknowledge that her father's not going to show. So she takes things into her own hands and calls a taxi to confront him. She finds him fishing in front of his house. He apologizes that he can't be what she wants him to be. She points to her reunion with Lux and says it's not a matter of being some idea of a parent. He is a parent. He had a baby. He can't run away from that.
Cate says she just wants her father in her life. His pained silence makes it clear that he's not up to the task. Ohhhhh, and then it all comes out. He only married Cate's mom because she was knocked up (runs in the family!), and they only had Abby to save the marriage. In the end, he just wanted to be an irresponsible bachelor, not a husband or father. He tells her he loves her but can't give her what she wants. Ever. Cate holds back the tears as the epiphany washes over her. All the displaced blame and anger she's been harboring toward Baze was actually for her dad all along. She says Baze wasn't the one who wrecked her. Grant was. She walks away, for good. She rounds the hedge to find Baze standing there with Lux. He admits he never left, just slept in his truck. She staggers toward him and crumples into his arms, crying 26 years worth of tears.
And so the family begins their road trip a little more distant from each other than when they begin. And isn't that always the way? Grace Slick sings about nothing stopping the proverbial "us," blissfully unaware of what irony would lie in her words 23 years in the future. Lux breaks the silence, suggesting they get it over with and talk about the bar, Bug, etc. Baze decides to put off cruel reality and starts a serenade of "Nothing's Gonna Stop Us Now" for catatonic Cate in the backseat. Lux joins in, tunelessly. Eventually Cate wakes from her self-pitying stupor and gets in the spirit, fully swaying and belting out the song.
They arrive back at Cate's, all outfitted in their corn dog hoodies. Lux makes an excuse to go back to the car, and Cate takes the opportunity to apologize for redirecting her decades-old anger at her dad at Baze. She appreciates that he tried to be honest with her and affirms that she always wants him to tell her the truth -- even if she doesn't want to hear it. Baze grimaces slightly at the truth he's holding inside that she definitely doesn't want to hear. They share a moment, then Ryan comes out to greet Cate with a kiss. Lux decides she should go back to the loft with Baze to supervise his talk with Bug.
