Top Ten: Martha Jones is Flawless
6. Smith and Jones (3x1)
The most extraordinary part about this whole scene is that Martha Jones proves herself to be worthy companion in the most ridiculous of situations. They’re transported to the moon and instead of panicking like her coworker (and everyone else in the hospital), she’s logically working out that the windows aren’t airtight and there’s more going on. Even the Doctor is impressed with her (“Very good point. Brilliant, in fact!”) and when he asks her to come along, she doesn’t even hesitate. How many of us in that situation, with that level of panic in the air, would have had the intelligence to come to Martha’s conclusions or the courage to follow a stranger out onto the moon?
