The Doctor stayed in the console room for a very long time. He didn't move, he couldn't move. It felt like the paradoxes in the universe were crumbling around him and if he so much as breathed in the wrong way, the whole of creation would crumble. It was the sort of pain he felt when any loved one passed, he decided. Only worse, because he not only lost Bea, he lost the life he might've had, and he lost Jack.

All in one go, that was a record for him.

When he finally got back up to his feet, he flipped a few switches on the console, effectively sealing the doors so Jack couldn't just leave. He wouldn't have him leaving over emotions, they almost lost him that way once. This time, if Jack wanted to go, he could, but he'd have to tell him later. For now, the Doctor would go into his room and lie there. He couldn't sleep, not yet, but he could lie and wait until the pain numbed somewhat. That would be for the best.
