So... Yeah. I've read everywhere that the companions can't die no matter what, but Hancock is in pieces. The settlement I was in at the time got attacked and the Super Mutant Suicider blew him up. This happened about a month or so ago. I'd send pictures but I can't find his pieces.

I tried looking for his corpse again, but between Strong and Dogmeat, I can't tell who could've pick him first. Jk. It's been so long he probably despawned. This really svcks man. I have all the followers except him, and Danse. He doesn't talk and he's stuck in Listening Post Bravo.
