[The disappointment he feels is sharp but fleeting, even though he agrees that the situation is far from ideal and really does complicate a great deal. Of course he couldn't expect her to be overjoyed, and if anyone had a reason to be disappointed, it was her. He knew he was shutting her out, even if he didn't make it overly obvious.]
I know. It is my fault.
[All the things he can't tell her are locked away - the bloodplay club Boyd had introduced him to, his knowledge of Van Helsing's true identity, the constant struggle between himself and Dracula - leaving a false sense of calm behind. Of course he wouldn't tell her that he was anything other than fine.]
Fine. Things have been quiet, which is good - how have you been? I missed you as well.
[Just how much he missed her was kept unspoken, demonstrated by a sharp pang of yearning. The guilt that lies beneath it, however, is carefully hidden.]
