"One trip in the TARDIS. Though I suppose we could... stretch the definition."
I've seen people talk about the whole "just one trip" thing Ten did with Martha as him leading her on or whatever and like in fairness it really wasn't the best way to treat someone, it was hurtful! but at the same time it isn't... leading her on the way people seem to think. it's him not wanting to get attached to someone else after losing so much so recently, but the entire time he's lying not only to Martha, but also to himself because he already is attached. do you get it?
