...But still had Trixie falling for her and having Dove after using a genderbend spell. What kind of scenarios could happen? Especially now with this whole "Nightmare Dove" arc being shown.

Dove having DNA defects?

Dove probably would've wholeheartedly accepted Nightmare's offer, wanting to sort of be like Starlight. Powerful and in control.

Now if that were to happen.................I dunno

But I guess Dove wouldn't hang out with Starburst as much, so just like what you guys said, Dove would prolly be happy to become Nightmare Dove

......or maybe we get weird magic stuff involved and Star gets the feeling that she's supposed to be friends with Dove
