As I said above, she's still in denial about her feelings about the Doctor. In SR, she's not. She knows that she loves him and doesn't want her ex there getting in the way of the development between them.
Exactly.
I think someone did a post many moons ago, asking when people thought they fell for each other. My belief is that it is during this episode that the Doctor realises he's in trouble (probably the well-quoted line from this ep, actually!). As for Rose, as you have said, I think she is falling for him just as fast (the little smile you mentioned, when he delivers that line is the a giveaway). However, I don't think she actually realises she's fallen for him until PotW. Which explains why she still views Mickey as her 'boyfriend' throughout S1, but describes the Doctor as being 'much more important than that'. She's still too young and inexperienced to realise at this point exactly what it is to be truly in love, and it takes her the whole of S1 to work it out.
