Theory on Q!Aypierre :
There is actually 3 different person in Q!Pierre's body :
-the old Aypierre (let's call him preQ!pierre), from before the island to just before the awareness of the federation. The trauma due to the acts of the federation made him forgot about his previous meetings with them. He's quite naive and scared about what happened to him.
-another Aypierre (wise!Pierre) that know what happened with the federation like the torturing stuff. He made the machine and wrote the books . He tries to protect preQ!Pierre from remember the torture and protect the body in general. He is aware of the 2 others one.
-ayrobot , injected as a virus in Q! Pierre's body to stole Aypierre's memories about his creation (ayrobot's) . He is trying not to get caught by other islanders. He hates his creator for abandoning him and wants revenge. He's only aware of preQ!Pierre presence.
More details bellow :
Here's the timeline about what I think is Aypierre's mind (English in ALT) :
Let's call purple!Pierre when they are only one (like a merger of them) with almost only the memories of the island (every Aypierre are purple!Pierre and have his memories)
after the plane crash Aypierre is purple!Pierre but doesn't remember his past at all . wise!Pierre is the first to remember about the past and want to help preQ!pierre to remember about his past but not about the torture he endured.
With ILoveYou.exe , each Aypierre remember their own past and keep their memories of the island. (When Aypierre wake up right after and say he remembers *everything* especially remembering about Ayrobot, it's was actually preq!Pierre who remembers creating ayrobot .
After that, it is mostly preQ!Pierre or just 'purple'!Pierre who interacts with other inhabitants. Ayrobot came during the purgatory to save the body and win (maybe to save Pomme too) (Aypierre speaking French was preq!Pierre having unconscious trouble to fight against the will of ayrobot to lead the body)
