Pauli continued to explain, "Even if we get there first, we can't get away with it without others finding out at the end of the day. So unless you are ok with people knowing that you are nabbing kids that just awakened for research, I won't advise it."
Kelvin was disappointed. He knew it was going to be difficult, but he was still disappointed by it.
He was only partly dissapointed with Pauli though. It is the fact that he doesn't want to draw attention from other people looking for people who just awakened powerful abilities that made him mostly disappointed.
He can't compete with them and he can't bear to withstand their scrutiny and investigation even if he succeeds in snatching a target from them. But he wasn't going to make that last part known to Pauli. That will cut off his path of retreat, which is something he doesn't want.
