It's the 'during' that he's worried about. That somehow the Heart had managed to sneak the parts in, disguised as items that weren't weapons. He'd seen a couple of members lingering around, didn't want to call them out or draw attention to them.

Somehow they could cobble together a bomb on the premises. But he knows better than to discuss that type of thing tonight; his searching he can write off as his duty as a law enforcement officer and not that his date is otherwise occupied for the evening.

So he just nods and raises his hand in resignation. "Right. Yeah. I know you guys checked. I just uh... had nothing better to do than double-check it. Sorry about that. This shit is fucking boring."
