>>95429753If Berserk is supposed to be the brainy sister of her group like Blossom is to her's, she would go a psychological route to really wrench out the pain.
After shooing Brat off and telling her to go play with the "boring pink one," Berserk would put on a show of being concerned about Bubbles's welfare. She would probably even untie her if she was too drained to pose a threat anymore.
Blossom would be forced to watch her sister fall into the arms of her evil mirror and cling to them for support. To Bubbles, who had been treated like a piece of playground equipment by her doppelganger, a seeming act of compassion from someone wearing her sister's face.
And Berserk would look Blossom right in the eye while holding Bubbles's trembling form, coddling her. Smoothing her hair and whispering that it's alright. Making her trust her.
