Of course Haymitch knows Finnick is there. Finnick is hard to miss, peacocking around like he does. Whether Finnick wants the attention or not, he gets it. Which, unfortunately, Haymitch knows a thing or two about himself.

He hadn't wanted anyone to witness that reaction, even if he hadn't been able to do much to prevent it. But at least if someone has to see it, it's someone who knows what's behind it. That's something he doesn't want to have to explain to anyone. How do you explain that to someone who doesn't already know it?

He turns and looks back at Finnick, saying nothing for a moment. "You might as well sit down."
