Ruby scoffed bitterly when he picked up on her paranoid looks. Like it mattered if he'd told Dean or not- the older brother had been gunning for her longer than ever, and if he was here- wherever here was- it wouldn't take long for him to find them.
Plus, she wasn't exactly being subtle. Ruby had no more patience for subtle.
"Some kind of portal," she parroted back at him. "That just happened to pull you and Dean through- five years from now?" The same force that tossed him into the gazebo now shoved and pressed him back against a support beam, while Ruby squared her small, but iron-straight shoulders at him.
"Try again. And you've got about five seconds before I start blowing holes in this place trying to make my own way back." There really was no answer he could give her, besides clear instructions on how to get things back to 'normal', that Ruby would be able to accept with any grace. The thought that she'd been duped into some kind of elaborate trap by the two of them (while plying her own) sat on a frayed nerve, but the possibility that it was all true...
That was what made Ruby very dangerous; everything she had poured her entire existence into, her reason for living, had been ripped away- when she was so close. Without it, she had nothing to lose.
