Well. That certainly looked like a Decepticon insignia being worn as a mask. Val's eyes flicked over Tarn's imposing frame, cataloging his armor and the damage to it, the hints as to his altmode, the double fusion cannon... Not a scientist, she felt secure in concluding.

Fortunately, she'd gotten Uncle Doom's force field up and running first thing for just this sort of circumstance. Sure, she could stay hidden behind one of the pieces of lab equipment--none of these guys ever seemed to look down--but in her own intellectual way, she was as brash and overconfident as Rodimus.

"Down here," Val said, stepping out where he could see her and waving one black-gloved hand in an amiable enough greeting. Megatron might be wearing the other team's colors these days, but the things she liked about him suggested she could get along quite well with his former organization if she had to.

Or, if his initial reaction of restrained disgust upon meeting her turned out to be characteristic, that was what targeted EMP bursts were for--assuming this guy was dumb and incautious enough to start something when she had the home field advantage.

Either way, it should prove interesting.
