"This IS unfortunate." Hux strides into the room, eyeing Finn with extreme interest. He was one of Phasma's once. FN-2187, or something alone those lines, he thinks, and now the man before him is here as a bargaining chip. It's not the sort of situation he can directly reveal his ties in, but he HAS submitted the information to his contacts already. It shouldn't be long before there's an all out firefight at least.
In that sense, Hux doesn't even have to lie as he glances him over. "A bargaining chip for the Supreme Leader. Or rather, for something he wants even more." With any luck, the coded message that Rey is the actual target has gone through too, and they won't be sending her. There's something about that woman that terrifies him, not that he would admit it.
"...You're Finn now, yes?" It doesn't make much difference to let him keep that bit of dignity.
