Did Ten really treat Martha THAT badly?
I've seen people argue about the Tenth Doctor's treatment of Martha throughout her adventures with him.
As I've watched the episodes, I really do not remember any moments of the Doctor being outright cruel to her, apart from the "Hardly know her" line in Gridlock, or him furiously yelling at her in a fit of impatience in Utopia. Those two are about my only examples...
As far as I'm aware, he only saw her as a friend due to the memory of losing Rose at Canary Wharf still haunting him.
