Get out and figure out your powers.

You put the clothes on and leave, moving quickly so you aren't caught. As you get out, you notice a note left in there, you take it and look at it as you and the rebel leave. After looking at it, it tells you that the power you were suppost to get was the ability to create things with your mind, although somehow, due to the cold of the chamber, the part with your name was frozen and fell off.

About half an hour later, once you are in the rebel camp, you tell your savior what the note said, and that the experiment almost killed you and that also it seems the incubation time for the powers to appear takes about a hundred years or so, so if you did get powers they would be active by now. "Good, try using them, they could be of use." the rebel said. You try to create something simple, but to no avail, you even think of the possibility of needed an image to focus on to create it, and also to no avail.

After 10 minutes of trying, you give up, only to have the actual power come out and surprise you.
