Juugo sits quietly for a moment. He's not sure how it wouldn't be a curse, but... Well, if he was safe all the time, Juugo thinks he would find the power useful. If this will make him safe, he'll try it. This man feels so close, but at the same time, there's something a little different. Juugo can feel it inside himself, but he doesn't feel an it inside the man. And maybe another person's it can't be felt, but Nagato has described it as built up chakra before, so Juugo thinks he would be able to feel it.

He'll try. He doesn't know what this will do, or even if he should--he wants to ask Nagato about it--but he can't leave, in case the man decides not to show him. Juugo pays attention, and when it's pointed out, yes he feels it. Energy? that's coming apart and changing. But he doesn't know how the man is doing it, exactly, or why.

"I feel it..." Juugo doesn't try to voice the 'but' there.
