Weird shit, Bucky. That's how. Ever-so-slightly meta, cosmically absurd, deeply horrific weird shit. That's his life, and there will probably never, ever be a more satisfying explanation forthcoming. These moments simply come and go unaddressed.

"It's... situational?" He offers unhelpfully, scratching at the back of his neck. "Sometimes it's take out the aliens and go home, but sometimes it's- more complicated."

Usually it's more complicated, in fact. Sometimes it's Donald Glover is secretly an ancient shape-shifter that controls a pain demon named Sagoth, sometimes it's find a bigger god to eat the god that wants to eat you, sometimes it's blow up the murder cult or sacrifice yourself on a ceremonial knife and convince Bill Murray to reset your town full of mimic plant people. But all of that probably isn't very reassuring or informative right now. Probably better to keep it simple.

"If we can figure out who actually made the list, we might be able to figure out the reasons behind what's on it. That might be a... slightly safer place to start?"

Just in case talking to the entity on the fourth floor lets loose a poltergeist, or it turns out to be a Skinwalker or something like that. Although... maybe Bucky could handle the latter, honestly.
