David Tennant on the the Doctor and Martha in The Shakespeare Code:
“The scene in the bedroom is interesting because he is apparently, surprisingly, quite callous, really. Very unforgiving towards Martha, very ungenerous towards her. But I don’t believe he’s doing that out of any malice. The Doctor is still taking it one day at a time. For himself, as well as in terms of his relationship with her." – David Tennant
"From Martha’s point of view, the sort of things that he says, and the signs that she thinks she can see… she might believe in her own little world that there’s a chance.” – Freema Agyeman
