Rolf, unfortunately, wasn't going away unless Dennis told him to, partly because this was his shop, and partly because Dennis was in a temper and that could be dangerous, but also partly because he didn't know this guy who had made his friend mope around and hurt his feelings a bit and that always made him rather, well, over-protective.
He did content himself to stay in the background, however, and let himself be taken as an unknown threat without actively doing anything to be threatening. Unless you counted him putting the large cage of large tarantulas down on the nearby shelf, which was actually only because it was getting heavy and he really didn't want to compromise the spell keeping them in by casting a lightening charm on it.
He did have to wonder what he could do to short circuit what seemed like a spat of very bad sexual decisions on Dennis' part since Paden had done what he'd done. He really didn't like to see his friend getting into these situations. He gestured, a small thing, encouragingly at Dennis when he glanced back, proud that Dennis was able to rein in his temper, which Rolf knew ran hot and fast though icy as well.
Rolf gave Wayne a small, tight lipped smile and a small, short wave.
