At a basic level, its guaranteed that neither Bella, Fiona, or anyone involved in this really grasped the situation fully, being retarded zoomers.
Maybe it is a case of not putting 2 + 2 together and thinking that there wouldn't be a shitstorm at leaking the audio file and that Chris would still be hopping on a plane to meet her at the brony convention. You'd have to be really fucking retarded to think that though, like CwC level retarded. Thats a big reason as to why something seems fishy with these texts, plus we do know that Bella is omitting/likely altering the texts as well.
If Fiona leaked the audio, but still imagined there was a chance that Chris would be hopping on a plane anytime soon, thats bottom of the barrel cognitive dissonance level of comic stupidity.
