The Doctor had been out and about, trying to find this missing twin. His brother had been in some distress and as much as the Doctor wasn't fond of either of them, he wanted to try and help. He could be petty sometimes but not this time. Maybe he was in too much of a good mood to let anything spoil it. Maybe he just felt like being a little on the confusing side. Either way, he had something to do besides work on calculations and space time theory in multi dimensional pockets.
Spotting the younger man from a distance, the Doctor stopped and peered at him. There was something a bit off about his movements. It was subtle, granted but the Doctor was a keen observer and he liked to notice even the most minute of details in everything. Quickening his pace, he darted over towards him and stopped a few feet away, in front of him.
"Well, there you are! I do believe your brother is looking for you" he said with a warm smile. "He's not very happy though, something about bleeding and a wheelchair... And exactly what is wrong with you?" he asked, walking closer to peer at him. Perhaps uncomfortably close.
