Top Ten: Martha Jones is Flawless
9. Smith and Jones (3x01)
As anyone can attest to who has spent just a little too long under water in the pool, the feeling of suffocating is terrifying. All you want to do is panic, but not Martha Jones. Not only does she keep her head straight (she’s running out of air and she still realizes that the Doctor has two hearts, so he needs double the chest compressions) but she is also completely unselfish. Instead of trying to keep the oxygen for herself, she gives her last breaths to the Doctor, in hopes that he will save them all. That sort of perspective and selflessness does not come easily. Furthermore, he hadn’t even told her the plan ahead of time, so Martha is going solely on faith in this weird alien who she just met not even half an hour before.
