I know she's all emotional and broken and her father indeed fucked up, but still, fuck you Miya. Her jumping to conclusions is understandable, but also very very irritating. Even with what he did, I can't help but sympathize with him more, knowing how much he's going through and how he's still trying to do something even after all that weight on his shoulders.
And the parents are absolutely no help either. I shouldn't have been surprised. His mother's a given considering she has a Karen haircut, and his dad's one of the traditional "men don't cry" type of people. I doubt his in-laws are any better now.
