Bull doesn't want to deny Dorian anything. He doesn't want to deny either of them this chance to be together, but his expression mirrors the resignation in Dorian's voice. It isn't safe.

"I don't know how long they've been following me... us. Kyst isn't safe."

And if they managed to slip the note into his pocket while he and Dorian were together, Bull doesn't want to risk a more violent message. He leans down to gently touch his forehead to Dorian's.

"I'm sorry, kadan."

He should be better than this. He should have caught this when it happened, before it happened.
