Don starts scrolling through Netflix while Kaz leaves
(It might seem like Don is mad but he's actually not saying anything because suddenly Kaz got all depressed and he thought it was something he said so he doesn't want to hurt Kaz by saying something wrong again. But he's not looking sad because he doesn't want people to worry about him and not to mention he pushes his own insecurities aside and ignores the fact that maybe he needs help too. I'm sorry I just feel like I had to explain that)
