The reflection node needs light shining on the object from close to the same direction it's reflecting. His suit is well lit on the back but you're not reflecting the back you're reflecting the front.

Try adding a light behind the mirror and turn off cast shadows on the mirror so the light can come through from behind it and light up his suit. Also as has been suggested, increase the raytrace bounces to 3 or 4. Also you don't need shadows off, but you do need to make sure each light is set for Ray Traced shadows and not Shadow Mapped ones.

For what it's worth, the whole scene is a bit too dark for ray tracing to bounce much of anything. I can see his suitleg in the mirror but it's so very dark that it blends into the background behind him. You might also try adding a wall behind him with a lighter color to reflect so that his pants stand out from the black behind him.
