I do agree. The EA persona was the one, I think, doing the daddy talk, exchanging young CSAM with another "female" name, etc., so you could be right. I will say, this is where KAK starts talking about the dates being off with his phones. Lying, probably, but who knows.Or was he the persona of EmilyAnne when the daddy stuff was introduced. Honestly it’s all so vile I skimmed over some parts. I got the impression he used the EA persona in an attempt to normalize deeply perverted behaviour female to female and the AS mainly to impress (good looking, rich boy).
The other person with access to that phone has a criminal history of harassment and violence. And there's the search for the address of a family KAK already knows where they live the day before ski mask guy. Who has Mondays off, according to KAK.
Just questionable stuff all the way around. Ski mask guy did know which bedroom to peer in to, so maybe that points to KAK, but who knows how long he was there searching.
