Well, at least one of them had been smart enough to cut the damn thing out. He's surprised to see her holding it though, stares openly for just a second. If she still has it, it's possible to still track her -- although, it seems, for the time being, there's no been repercussions to the fact that one of the victors had lost their tracking device.

"Still got something sharp?" Finnick asks, turning his arm toward her so that she can see he still has his.

"We could try getting one of them," Finnick suggests. "Chucking it into one of those magic doors." The truth is, to him, it seems only slightly better to have it out of him and in his hand. He'd rather just be rid of it entirely. Of course, if Katniss and Johanna still have theirs, it doesn't make much difference. They'll find him with them -- but with the trackers out, it does leave some room for ... experimentation.
