Okay on one hand Mike is So Fucking Done with this Richie thing already, and he kind of wishes he'd never found out about it because it's weird and uncomfortable. But also, this kid seems like he really needs some friends? Mike doesn't necessarily feel sorry for him, but he does feel like he should go easy on him, especially once he brought up his mom. While Mike has absolutely no understanding of what's going on there, he does recognize that it's Some Serious Shit and Eddie probably could use a chill group to hang with, instead of going it alone here.
