I'm currently rewatching the Rose Tyler era of Doctor Who and all my timepetals feelings are back
Fools fight over who's better between ninerose and tenrose when you can't have one without the other!!
Ninerose was the era of falling in love, it was banter and teasing, and it was mostly focused on the two of them, so it really made it so intimate and special. You see firsthand the impact both had on each other, with Nine's character development. How he doesn't do family but alters the universe to keep Rose's father alive. How he says he doesn't care about idiot Rickey Mickey but he'd invite him on the TARDIS so he can look after her.
You see how they hold each other close to their heart, how they lose themselves in each other's presence. Holding each other's gaze.
Tenrose is an already established love but now with a totally new face, so both of them pulled back a little for the sake of the other. You get such a shyer love, with a lot of physical touch but unfinished sentences. You get promises. Stolen glances.
The way Ten says "and it is gonna be...fantastic" on the first day of his regeneration because he wanted to reassure Rose that nothing much changed.
The way on that same day, she invites him over for a family Christmas dinner, fully accepting him.
The way he asks her on where to go next and gets lost in her expression, still processing the pure joy she has to be traveling with him, that she truly doesn't mind. That he didn't lose her.
And this dynamic works so well because we had ninerose before.
"Just tell her... tell her... oh she knows."
