[@LuckyBlackCat] - I was thinking that since Sophia referenced Tokiko it might lead the topic to the Magical Girl Chatroom. She doesn't know of it yet since she's a recent arrival but once she does it may mesh nicely with her distributed network of eyes.

As for the conversation itself I do not mind them continuing on the discussion. Whether or not you wish for Fuyuko to remain to speak with Sophia longer or split off to interact with others I'll leave to whichever suits your preference. Sophia will be around either which way, analyzing the situation and learning more of her fellow magical girls so that she might see to it that the more dangerous competitors are eliminated first.

Or perhaps turn her eyes to the more secretive elements surrounding this event. Try and gleam more of what might be watching back.
