Not the sort of question he expected but nothing should've surprised him. If HYDRA was planning an attack against Genosha then good luck to them, they'd sure fucking need it. If they were allied with Genosha (and Nick sort of thought that was hard to believe) then he could see why she'd want the information but the last thing he wanted to do was help HYDRA and Magneto.
The first generalized part of her questioning got a snort from him and he shook his head. When she'd finished he couldn't help but point out in a mutter, "That's three questions" before he began answering before she got her panties in a twist again. "We've got agents in Genosha, a lot of intel. We know most of the Brotherhood roster-" he stopped himself. It wasn't a 'we' anymore so he amended. "They've got the layout of the island. There were small invasions in the past but we've never planned anything wide scale. That would be fucking stupid."
