Celeste's mood didn't improve once she was outside. There were less people looking at her, that was true. However, she temper was rekindled when she realized what all the trouble must've been about.
She came to the conclusion that it had something to do with the photo Jen sent her. If it was floating all over social media, of course people would see it and be curious about it consider moderate level of fame Bane seemed to have.
Why was it that ever since she had met she had encountered nothing but trouble? Did it have something to do with whatever the curse he had was?
Whatever the case was, Celeste knew that she was going to have to have a discussion with him at some point in time about leaving her alone so that trouble would stop following her everywhere.
Plus, if he really did have a fiance or whatever that crazy woman was, she wanted to put her foot down on the fact that she knew and wasn't interested in creating the wrong impression with someone who was already taken.
