Finnick knows that a lot of sophisticated things can be done with machines and computers; that's apparent to everyone from the districts even before they first see that technology in action, even if they never travel to the Capitol. Finnick's known Beetee for long enough to be able to understand a little technical talk, but he usually pretends to understand more than he actually understands.

"They don't seem very aware." He says it tentatively, almost as though he's seeking her agreement or approval, though he really needs neither.

He does want to understand more about the bots though.
