I love how Carl's love for Donut and Bea is shaped by the love he's felt before. being in denial about how much he cares about Donut because last time he cared about a pet, it was taken from him. not realizing how bad his relationship with Bea was because being shut out, yelled at, having stuff thrown at him were all things his parents did too. Carl only recognizes the "drama" in his relationship with Bea when she cheats on him because no matter what happened with his mom, dad, or fish, Bea is the only person to ever hurt him in that way
