I think they've bonded awfully quick. If Dani is so put off by Todd and wants nothing to do with him like she repeatedly insists, then you would think that she wouldn't be all that gung ho about buddying up with Starr, since that would just put her in closer proximity to Todd. Beforehand I assumed they'd be rivals too; I assumed that Dani's anti-Todd feelings would negatively color her first impressions of the rest of his family, that she would have an attitude around them, and that her rants meanwhile would irritate Starr. I figured they eventually bond, but I didn't think it would happen so quick.

This could happen, Dani and Starr could become rivals when Dani finally accepts Todd as her daddy and then gets all cuddly with him, Starr might not like that and maybe that will start the sparks flying.
