He was preoccupied. Martha could understand that, oh how she could. Every waking thought she had, and they were many because sleep was an issue, was of Rose and Tony, where they were, what they were going through. In one go she had lost her boyfriend and her best friend, and she frequently felt as though she was going to completely lose it.
"Hey, we're a curious species, us females in particular." She smirked as well, though hers was much less manic. "And how can we resist, a mysterious stranger comes along and invites us to see all of time and space. Not many could refuse that." She hadn't. A mad man in a box, offering her everything, and she had taken it.
"Rose still hates you calling us apes," Martha reminded him softly. "She's lost, not gone. We're going to get her back, her and Tony and the others. You have to hold on to that." It was what Martha told herself every day, repeatedly, or she would go mad herself.
