I would say you may think I may be crazy as when you all read the title but hear me out. Gregory had far more therapy than Vanessa and his first therapist went missing 5 months before GGY and if you see that Gregory has 72 sessions and that is 1 year and 5 months if you know he takes therapy on Sundays as again in GGY he never tells his friends what he does on Sundays. And he is 12 in GGY and 12-1.5 is apparently 11 years and 7 months hinting his therapy begun after his parents deaths as his childhood is brought up but his first therapist began in 3 years so implying he started 3 years before GGY and that he had 72 sessions then it could imply he lost his parents at age 8 and months and he may have not started therapy at once but may have lost them at the age and started therapy after he was under Glitchtrap's control and may not have been trauma as it's mentioned more than seriously addressed to the client. He would also straight away not get therapy but he was terrified at his parents death but when he was asked about their deaths he read it like a book so implying that he may have been possessed either before or not long after their deaths. But also that Gregory is mentioned in the CDs to develop software programming that repeats and talk phrases and also that it's something that the Mimic does and also he may need someone high and powerful position on the Pizzaplex or Fazbear Entertainment to merge with and that's why he ordered Gregory to make those tapes with the software programming he taught him and those tapes were Tape Girl's and also if you listen to Tape Girl's voice it sounds like Gregory but more feminine and adult-like so he could have changed his voice and also that Mimic may need Gregory as his favoured apprentice may be because he is a kid and no-one would suspect children being used as an ally and also that he posses hacking skills which adults won't suspect kids for such enhanced abilities and he may also want him to get to Vanessa or a beta tester that has a high position like Vanessa and to get close to his goals. And also Scott is creative with his plots and making Gregory is Tape Girl would be a smart thing that he did as no one even suspected for over 5 years which can be a big deal! Also it's no wonder Gregory does all these things he lost his parents at such a young age and Glitchtrap took advantage of his trauma as his chance.
