Episode 4: Sometimes You Can't Live Without Dying, Baby
The zombie Stiltonian the crew turned to for advice after getting zombified by it apparently got a job at the movie theater. As the undead crew move in to take their seats, a zombie hunter comes in soon after and asks for a ticket. Catching onto the charade, it bites him the second he sticks his hand through the hole in the ticket booth's glass.
Episode 5: A Merry Companion is a Wagon in Space, Baby
Dandy and his interactions with Adele, the little alien girl.
He becomes more and more like her big brother. It's especially heartwarming when he stays up all night and finds the little alien girl's grandfather.
The last scene has one of these after another. Dandy decides against taking her to the Registration Office despite her worrying about all the money he spent tracking her down. Then she asks to join his crew and he more or less says 'you can when you're older'. The final lines in the episode cap it all: "I'm gonna grow up quick, and when I do, I'll be the one hunting you."
Episode 8: The Lonely Pooch Planet, Baby
Dandy and the gang's interactions with Laika. As opposed to Spike, who "hates dogs, women and kids", these seem to be the only things that influence Dandy to do pure-hearted deeds for once.
Episode 10: There's Always Tomorrow, Baby
Initially, Meow isn't too keen on wanting to visit his home, saying that he left because he found life there too boring. Over the course of the time loop though, Meow decides to use this as an opportunity to reunite with his father and at least attempt to try and learn more about the job his dad works in (a job Meow didn't really want to go into). By the end, Meow feels like he's become much closer with his father, and when he's leaving he gives a heartwarming goodbye to him, his father saying he doesn't mind that Meow choose to explore the universe instead of becoming a metalworker.
Hell, Meow's father isn't just okay with Meow following his own path, he was downright proud of him for it! The barkeeper mentions Meow's dad brags about his son every night he's there, about how brave and special Meow is.
Episode 11: I'm Never Remembering You, Baby
Subtle example, but Bea is prominently shown being concerned for Gel's well-being. Bringing him tea and asking him to take breaks, actually stopping being a slob for once and trying his best as a replacement, and not abandoning him by evacuating when Gel's going crazy in the end. This is especially noticeable when you remember Dandy didn't really give a shit when Meow seemed sick.
Episode 13: Even Vacuum Cleaners Fall in Love, Baby
