Trahearne's expression was very blandly polite as he listened, he didn't want to show any amusement. Well that would explain the mood, seems Tannusen hated admitted his feelings more so than Trahearne had thought, even after Cassian handed over the note. It was almost endearing if it wasn't so frustrating to deal with. Especially while he was off killing his other half like a maniac!

"It's a pleasure to finally meet you Cassian. I wouldn't worry that you've upset him, he handles many things in an odd way. Such as only calling you 'The Catholic', a term I wasn't even familiar with at first. I am Trahearne, so now we both at least know each other's names." He rubbed at the back of his neck and looked over to the kitchen. "Are you sure you don't want anything? There's not much I can provide in way of distraction right now unless you want food or a book."
