But he didn't have that luxury here. This was Hermione's mind, pure and unaltered. There would be no tether to the outside world, or any other person. Harry was actually glad of that. He was ridiculously possessive of Hermione now and didn't like the idea of sharing her with anyone, but he still couldn't inhabit her mind forever. If he didn't eventually drive her mad with his lingering presence, she'd probably assume he was brain dead and they'd kill his body. He couldn't let that happen, not after coming all this way with her. He had to find a way out. This was going to take some thinking about. Harry sat down, drumming his fingers on his chin and humming tunelessly as he considered the problem.
