Alright, now she was not happy. Not even close. She caught that laugh of his easy enough, but the water balloon? Oh no. She wasn't about to let him get away with that. Rogue had a bit of a temper and she wasn't one to let someone just get away with picking on her. She hadn't been that way growing up, and even with her powers, that was not about to change now. He had started this, for whatever reason and she was going to make sure it was finished, at least on her end. Fair's fair and all that.
She saw that water balloon coming at her, unlike those damn poppers. There wasn't anyone around to see her fly, and so she did. She flew towards the water balloon and caught it as gently as she could, keeping it far from her own body, in case her catch didn't work out as well as she had hoped.
Quickly catching up with what she could see of his shadowy moving figure, she smirked, dropping herself down behind him, water balloon in hand. "Not one for introductions huh?" Rogue called out to him. "Because I'm thinking maybe you are the one that needs to cool off," she teased before launching his little prank right back at him.
