Nina saw through him, even if she didn't know exactly what she was seeing. Really, it isn't too hard to catch onto Finnick; there are always times when his mask cracks, or when he says something so offbeat and cynical that even his charming smile can't cover up the dark undercurrent beneath it. She isn't the first one to notice, but she is the first to blatantly call him out, the first not to play into his flirting. Hell, there are people here he fucks regularly who don't know any of what he just told her. If people want to keep it surface level with him, he will play along, but he does silently judge those who don't make an effort to get past his facade. When people push through the niceties and ask him about the horrors, it shows they really care, that he's worth more to them than just a quick fuck or a flirtationship.

Despite her aggressiveness, he's glad in the end that she interrogated him.

His gaze is cast down at the table now, a sad smile on his face.

"Thanks," he says quietly and sincerely. "It's fine, though. I'm fine now."

Heavily debatable, Finnick. He inhales deeply through his nose and looks up at her again, as though to snap himself from his thoughts and break the tension.

"I'd love to say all of that is why I'm annoying, but truthfully I think I was born that way." He grins.
