I have no doubt that Chris is easily fooled and/or perpetually confused.
What really fucked with my head was.
we used a voice changer on billy, we made their voice really high
yeah we raised it to sound like a girl for fiona
This makes me think that either the goal was to sound like Fiona or that Fiona isn't a female.
We have clips and a story of an autistic girl who is supposedly Fiona.
One of these clips is her facetiming with Chris.
The story is that Chris was in communications with her specifically making plans to meet up at the Con.
I feel like this would lead to enough communication between them in this specific time frame that even Chris would question a guy trying to pretend to be her.
The possibility of Fiona being trans and using a voice changer after reconnecting/reaching out to Chris would make it more likely that someone else using a voice changer could get close enough.
But this means that the "just friends" and "completely caught off guard" story line comes under more scrutiny.
If you were just friends with Chris and weren't out to troll him why would you find some troon in his orbit and convince them to use a voice changer and record communications with him?
I'm sus of these kids but not sold on the idea of them actually coercing him into this, I think the truth may be somewhere in between the two prevailing theories.
I think they were out to troll him, they had something planned (Maybe for the con) that would have maybe been funny maybe been terrible, they got a hint of this and floundered unsure if they actually wanted to scratch the surface and see what was really going on, they did and were not only upset by it but the plans they had getting ruined by it as well, and finally more or less did the right thing and now we are seeing them try to distance themselves from the situation while also covering their tracks for whatever the original plan was.
