Dalton probably does well in jail. There's structure, he gets fed, and with his weird cop fetish, he probably thinks the guards are his buddies. He's probably an okay inmate. I doubt he's making friends in there though. He's weird and obviously crazy. But with him being into men, he probably has a few people who at least tolerate him.
Honestly, my favorite thing about Laura posting full body photos of Sammie, was realizing that she only wears those sad lunch lady Walmart sneakers. They're the shoe form of giving up.
