This is Rev with her second character! Alex Summers - Havok. The younger and less polite/uptight brother of Scott. He's been on the run for a couple of years and has come to the institute after seeing how things have been going. He semi resents Scott but wants to be able to watch his brother's back. He's got a tendency to get himself into trouble and his power is not nearly as stable as it should be.
The PB is Jensen Ackles and I'll probably post an intro thread for him shortly.
