"Charles: You don't understand, it's not a question of being "rusty!" I can flip the switches, I can turn the knobs, but my power doesn't come from here [points to his head], it comes from...here [points to his heart]. And it's broken. I feel like one of my students. Helpless. It was a mistake coming down here , it was a mistake freeing Eric, this whole thing has been one bloody mistake! I'm sorry, Logan, but they sent back the wrong man!"
