@wolfeng It makes more sense if you look at it as a slip of the tongue; he was terrified and babbling, she implied she wanted to hear everything he saw with his Analyze, so he spit out everything.
@wolfeng I'd say it's pretty common for men in manga to be "tactless" about things women would prefer you don't talk about. Especially if the woman is likely to react in a comically violent way.
This is why I can't watch Saw, or kidnapping movies, it's just too believable that terrible shit can go on, and your friends will just wander off without noticing. 'Looks like your friend still has somethings to talk about with the boss/principal/priest, but we got some food and candy in the other room, wanna come along?'
