Ask Lucy for toilet paper

"Wait, this will be Juvia's problem, so it's okay!" Erza/Juvia exclaimed as she knocked on the door to get Lucy's attention. "Lucy?" She asked sweetly. "What's wrong, Juvia?" Lucy asked. "Can you pass me some toilet paper?" Erza/Juvia requested.

"Oh, yeah. Your butt must be a mess after that explosion!" Lucy said, laughing, much to Erza/Juvia's anger. "Well, can you give me some, please?" Erza/Juvia asked.
