Rodolphus appreciates his restraint. Sort of. No one is forcing him to drink and abandon all vestiges of dignity by being miserable at Antonin. He's choosing to do that of his own free will and the alcohol is a necessary component.

"He is at least not a traitor." Which is such a kind comparative assessment of Lucius Malfoys, but coming from Rodolphus, it might as well be a ringing endorsement.

It's hard to imagine Severus with a dog. He tries, as he takes a very long first swallow of something that feels like it's dissolving his esophagus. "Sobek Croix. We work for Hellsing. Is it. A small dog."

Seriously, he's having a hard time getting over this bit of information.
