Excellent! The Corps might look on his...extras...a little more leniently than the general public, given they're all different in various ways. He's just a little more obvious in it.
Gabriel was taken into custody when he was fifteen, and he's thirty-four, so he's out-lasted many teammates. He's comfortable with who he is now, and he's fairly friendly, at least on the surface. Reaper might make others a little nervous, but Gabriel definitely would.
