[@LuckyBlackCat] - Do bear in mind that Sophia is not a front line fighter. In any particular confrontation she'll flee and attempt to establish a hiding spot so she can take care of the threat remotely using her magic. If shades are introduced the odds of them having a post-fight conversation will be low. It was pretty unlikely for Fuyuko to find her the first time and it largely fell upon the fact she has a sister with undisclosed powers as a result of her lack of a CS, one such power being the ability to locate her. Given how dangerous it is for her to be seen and involved in matters directly I can't see Sophia letting her guard down purposefully in an event such as that once her hiding spot's reestablished.

It's yours and VitaVitaAR's choice of course. I can only control Sophia's choices in any particular event.
