Leander was having a hard time believing what the Doctor had just explained. He wanted to be rational about this, but the whole affair was way too bizarre for any cold calculations. His instincts told him to stay as far away as possible from this bringer of ill news, but the fellow was really growing on him. Besides, the man had been nothing but nice to him and this was really hard to come by these days.

"Hold on for a moment. You wish that I leave now? I'm afraid that isn't possible. Firstly because you've been kinder to me than anyone in a long while. You ask my opinion and treat me like an equal being, not like a disabled person. For that I am immensely thankful. And secondly because you've told me some crazy things and I'm not leaving until you explain every detail to me. Understood?"

Leander crossed the distance between them and stood close by the Doctor's side, smiling confidently and tapping his heels together as a sign of readiness. 

"You really have to do better than that if you want to get rid of me. I'll come with you and you'll be surprised at how well I can defend myself."
