Christopher was deliberately being an ass. He does it when he's angry, or tired, or when he is with Adrian. A part of him thinks that he should be fearful for his wife's life, getting shit together, planning, breaking down doors and bodies. Not sitting here drinking beer.
"Sally-Ann," he said flatly, not really expecting a wave of sympathy from Adrian. In fact, he'd appreciate it if there was no sympathetic wave of any kind. Thank you very much.
Sympathy wouldn't get his wife back. Or even give him answers.
