[ Yet. Though really when Marceline makes a "threat" it's often just her creepy way of being helpful. There's a flicker of surprise on her face when she sees the gun (such things are practically relics where and when she's from) but there's no alarm or worry. Just curiosity. ]

No offense, but you don't look like the type to spend your time meandering around museums for kicks. Unless you take things from them. [ Her grin widens. ]

Nice name. I'm Marceline. As for these guys [ she glances over into the fog ] I have a feeling they're only the beginning of whatever's here. Ghosts, apparitions, whatever don't usually pop up for no reason. And I'm guessing they weren't invited here to party.
