They should get to make each other miserable for like one issue and also I think Tara's fate and the way the titans speak of her should haunt them forever and they should terrify the hell out of each other. Mia listening to the other titans explain the story about Tara while trying to remain composed and stoic while Rose is listening and biting her nails from behind the door

Also at least one of them should have a sex dream about the three of them and it's not even a nightmare the dream feels good if weird and then she wakes up drenched in sweat with tears in her eyes because she only remembers the first part of the dream and then she doesn't remember what she dreamed after but it was bad and then she gets up and practices until she's not thinking about anything anymore

I think also maybe Rose should have some sort of nightmare/hallucination about Tara's ghost kissing her while being on fire and holding her chin and whispering in her ear about how slade called her her name once while they were in bed together
