Okay, so this could be a problem. Admittedly, it is a little strange to see Hux this way, but if the resistance can sneak around and have spies somewhere, then it makes sense that the First Order would too. He just wouldn't have expected Hux to do it personally.

He hasn't got a weapon of any sort, which hopefully won't be a problem. Someone here must have one, anyway, if it turns out to be necessary.

He keeps his head down until Hux passes by him, then waits a few seconds and follows quietly after him, intending to do a little reconnaissance.
