It's... not like I can tell? It just feels like... I dunno, the atmosphere is a little different? Maybe you just seem upset...?

[Due to Nightingale's life, she's become somewhat... hyperaware of when people are upset. It was an unfortunate survival tactic for her, since her parents' moods controlled her entire life. She second-guesses herself constantly, but someone being obviously upset has her on edge automatically, even if she isn't conscious of the exact signs herself.]

Seriously, though, are you all right?
