Cassius Corbet
Cassius is very, very interested in the identity of these conspirators, and is privately delighted that he's been given two for the price of one. He is, by turns, annoyed at others for being useless and worrisome, and unable to help making catty comments even though he's aware they aren't helping the situation. For what it's worth, he is, for him, actually being restrained and making an effort. The unavoidable verbal byplay with Swinton is positively playful by his standards. They are, after all, currently sharing a common interest.
Cassius would like to know what the conspirator's wishes are for this little confrontation; what anyone else's wishes are for the same; how much damage is considered necessary or even preferred on both his side and the assailant's; and what the Night Watch is doing here, and is it anything useful.
