The idea of a werewolf coming along into the Aurors' office wasn't exactly one Cass liked to hear, though he kept his mouth shut and thoughts to himself. He knew many felt Remus was trustworthy, that he was acting headmaster with Minerva in a coma and that he was high up in the Order. Still, he couldn't ignore that he was a werewolf. The same kind of beast that had nearly attacked his mother not so long ago. The mere thought of them made his skin crawl.
He was not a Slytherin for nothing though, and he did know how to keep his thoughts to himself and only smiled in response. A smile that turned into a chuckle as Tonks nearly stumbled over a stick. 'Nasty things those sticks,' he teased, blasting the stick from the road while winking at her.
He did smile wider when she talked of taking on more duties. Not because he wanted her to spread thinner than she already was, but Merlin they needed the help. 'I can't tell you how useful that would be,' he said warmly.
