Well, Ash wasn't wrong there. Rook had no idea where he had been leading them. Even if it was back to his apartment, the Gangrel had only ever flown there, never worried about how to get there from this vantage point. Of course, none of that mattered with what Ash said next, teasing or not.
Rook looked at him then back down at Ash's lips. It was clear that he was considering his options. For a moment it seemed like he was going to reach out and run his thumb over them once more but instead, he slid his hand around the back of Ash's neck. He used that hold on the Toreador to pull him in closer before he did take Ash up on that offer and kissed him, claiming his lips with his own.
