Possibly the best Series?

[Nia M]

I think it was the fact that they were about to die, and thus had that moment underwater

Spoiler: show

where they (I believe) admitted that there might have been something between them. I've always thought that if Ros weren't Ros then a relationship between the two of them would have been likely from the onset, but since she's who she is, Ice Queen and all, it did make it less likely. Then that moment underwater came, and Adam saw her without her barriers up (no pun intended on their location at this point) and that was really what was stopping her, because she didn't like the thought of losing that image of her. He'd seen it then, so that wasn't a problem afterwards, and so she didn't push him away anymore.

I like the fact that for once it didn't end on a cliffhanger, because it meant that they were able to immediately launch into the new series, instead of having to tie off loose ends like all the other first episodes. Sure it adds to the suspense, but to me the whole point of a new series is to start a new idea, and a new plotline etc.
