"When Rose meets Sarah Jane, she just hates her, she HATES her and i would frankly, i hate meeting ex girlfriends/timetravellers. Anything to do with the EX is just awful. She feels like shes lost the doctor once before and when you feel like youv lost something you become very..possesive in a way and she dosnt wanna lose him again and she becomes - yeah the possesive girlfriend, this is a threat to her when she meets Sarah Jane. What if he was in love with her ?, what if hes took this girl of traveling with him ?, what if shes a better time traveller, what if she can pull out all the stops, what if she can sing dance and juggle all at the same time?. You know its all very scary for Rose but then Sarah Jane is equally as jealous and they are both...yeah there is some serious bitch fighting in there"
