F10N4 might’ve had a part in the process of putting CC back together with Afton.

Dreadbear brain tinkering minigame with the mad scientist is present in R&D and F10N4 is inside R&D where we know she was present in the office.

We also know F10N4 & Afton had to meet in some sort of way since F10N4 was in standby mode and we also Know Fazbear took over MCM and its Assets with obviously the Murray household which is now owned by the Aftons.

Though the most weird part of Secret of the Mimic is the FNAF 4 call backs with David’s room and toys. Though also foreshadowing the Afton family under Flower Aftons.

However there’s motives at play here, F10N4 wants David Back under M2, with Afton wanting to put CC back together through Dreadbear. Which F10N4s idea of getting David back is Through M2 with obvious MM call backs inside Moon.EXE. 

Which after putting together Moon statue in Moon.EXE you go through a similar scenario to Happiest day giving the MCM animatronics or the Main bosses of SOTM like Dollie, Jackie, Big Top and chica their desired items making them happy just like in happiest day giving the MCI the birthday they didn't  get to experience in reality.

So in my mind, I think that when William came in contact with F10N4 he and she promised to put their sons back together in some way which is showcased in the Dreadbear minigame inside R&D. 

he has no left Arm he replaced it with the Quest Sword.

I think William using Willcare is trying to put CC back together with M1‘s Code.

since we know William would’ve had to have met her. which we know she wants David back.

so what if William wants CC back so they both come to a unstable agreement to try and put back together CC in the version of What they both want.
