I love how Rose is trying so hard to look at both of them, still trying to wrap her head around the fact that there are two of them and they are hers. But then… she settles her (rather sultry) gaze on the one that is actually holding still enough for her to feast her eyes on, after so long apart. I can only imagine the look he is giving her…
This is my refutation against people who say she didn’t want to be with tentoo.
And it is my belief that she wanted to be with both of them. But right then, Tentoo was taking full advantage of Ten leaping around, giving instructions… So he was making his move, and Rose was obviously quite happy to go along with a bit of very suggestive flirting.
