Lancelot flickers a slight from at that, because it isn't... good.

"You can't be happy that way," he ventures, because living a lie is never a happy thing. He circles his drink idly, takes a sip as he thinks. Can it really be so? It might be that Finnick has set himself up to believe it, but there might be a way around it? Or, even, it might be as simple as enacting the change in the way things are himself?

Lancelot is always an optimist though, he believes in a better world and in helping build such a thing if he can.
