That was not a reaction he expected from her, needless to say. With one very quick glance back at the WEAPONs, Finn puts a hand to her back, not too low or too high, and starts moving. He wants to get out of here quickly if they can without causing a scene, so his first few steps are a ground-eating trot he'd learned in the marches, testing to see if she could keep up like this. If so, they should be out of here in no time, but he'd slow up if he had to.
