John liked to think he was prepared for a good many scenarios, that between his mom, Derek, Cameron, as well as Callen, Sam, and Peter, he had a pretty good foundation for survival -- especially here where there were no killer cyborgs on the loose so far as he could tell. (He hadn't yet given up looking for signs of Skynet daily, just in case.)
Gunfire strafing the house? Covered.
Someone accidentally tripping the explosives he and Westen had been working on? Working on contingencies.
A trip eight stumbling through the rifts and into his bedroom? Expected.
A raven flying through his open window and then expanding into Brian? Not so much.
By the time his friend spoke, surprise had already pushed John from the bed, where he'd been sitting while he crammed for the certification exams on Friday, to stand with the bed between him and the window. His gun was in his hand, half-drawn and ready, but it took a moment for him to recognize what exactly had happened and to lower the weapon. "The hell, Brian. Don't do that." Returning the gun to it's usual place behind his back, John focused on just what had happened.
The raven had turned into Brian.
Brian could turn into a bird.
"Holy crap. That's just..." Yeah, superpowers in generally were looking pretty damned cool. "When did you learn to do that?"
