A/N - There's something not right about any of this.
A cloud of pink, glitter and a strong smell of candy and Wilford and Bim are on the roof. Sure enough, a short way off, toes on the edge of the roof is a complete stranger, grey shirt, colorful trainers, brown hair. You know he looks kind of like Marvin, though there'll be time for that later.
"Hello?" Bim calls, carefully edging closer, worried about startling him in any way. The guy doesn't respond. "Hello? Are you okay?"
Bim can feel something, an unfamiliar touch of magic that doesn't belong to anyone in this building. It's not the sugar of Wilford, the hollow emptiness of Dark, the fresh feel of Marvin's or that strange corrupted sensation Bim gets whenever he goes near Anti. It's something different, and it's not coming from this guy, but it's all around him.
The stranger's eyes are vacant, staring straight ahead, obviously seeing nothing. Evidence all points to some kind of mind control. Probably not very strong. They could probably wake the guy up just by giving him a shake. Bim glances over the edge of the roof. Yeah, that's not happening.
Wilford frowns as he steps closer, though continues to keep his distance given how clumsy he can be. The pink man frowns, able to feel the strange taste of magic as well. "Dark isn't going to like this."
"We'll worry about him later." Bim shuffles adjusting so he has a firmer stance as he reaches across, placing a wide flat hand firmly against the stranger's chest. No response. Bim takes a breath. "Please don't panic." he half mutters as he uses his magic to brush whatever it is away.
There a few silent moments in which the stranger slumps into Bim's hold, but the silence is broken as the man blinks, and then screams. He's aware, he's awake, and apparently, he's freaking the fuck out. As he tries to back away from the edge he stumbles, his feet slipping off the roof and before anything else can happen the man is falling. To hell with gentle! Bim grabs for the grey shirt, fingers barely catching, but he's too late.
Wilford's arms wrap around Bim's chest and yanks him back, unwilling to allow his friend to follow after. They fall back against the roof as the shirt is torn from Bim's fingers. They can only watch as the panicked stranger who'd appeared from nowhere on their roof begins to plummet to the ground.
