I am not sure if this is a popular opinion but I really prefer the Tenth Doctor to the Ninth as a love interest for Rose. In fact, I have been a fan of the Ten/Rose pairing ever since “New Earth”. Honestly, I never really bought Nine as a love interest back in Series One, but there were episodes that rather forced me to perceive him in that way. (Think “The Doctor Dances” or “The Parting of the Ways”.) Ten is a better fit, in my opinion. I am well aware though that romance is not really the point of the Doctor’s need for companionship, but I am glad that the writers have been exploring this for a while, especially in Series Two. Rose and Ten work well together and complement each other as well. Plus, I personally think that David Tennant and Billie Piper have really good chemistry.

Although both Rose and the Doctor have already been quite flirtatious in the past few episodes, for me, “The Impossible Planet” – the eighth episode of Series Two – somehow elevated their “more than friends, less than lovers” status into something more. Again, just an opinion.

In this episode, the TARDIS lands in some sort of station located in an unknown planet. This station is manned by a crew composed of real humans and their servants – creatures known as the Ood. The episode gets its title from a very strange occurrence: The planet, which at this point we know as “Krop Tor”, orbits around a black hole, and from science classes back in elementary, we know that this is an impossible condition. The crew believes that what’s keeping them from being sucked into the black hole is a great power coming from the core of the planet. Because of this, they have been drilling their way towards the center of Krop Tor in order to retrieve this power for the good of mankind. However, when the station gets hit by an earthquake, the section where the TARDIS lands falls into the core of Krop Tor. Rose and the Doctor, therefore, have no way of going home. Thus, they have no choice but to help the crew in their mission, so that they too may have a chance of finding their way back.

It is in this distressing situation that Rose hints that she might want to be more than just the Doctor’s companion because really, at this point, they are just hoping for the best. But what if they don’t ever get back? What if she never gets out and eventually dies in this planet? It is not exactly a life-and-death situation, but at times like this, Rose finds herself very vulnerable. Therefore, she does not hold back and just allows her emotions to flow. In “The Impossible Planet”, Rose and the Doctor really do seem to look and in a way, act like a real couple. I do not know how long this is going to last, but I have to say that I am enjoying the current state of their “relationship” nonetheless.
