As a teen he bullied CC, and we know as a fact that William at least neglected he's kids. Wich may be the cause, NOT AN EXUSE of Micheals actions. He was sorry for the bite (the end cutscenne in fnaf 4 the same colored lines as mike said "I'm sorry" wich hint that mike do in fact felt sorry.)

We know that William at some point got missing (he got springlocked and nobody found him so he was propably labeled as "missing"). Did he know about he's father being a killer? We don't know, theyrs a big chanse that he in fact was nightguard in Fnaf 1, and if we follow that it means he changet he's last name to "Shmit", wich can chave few causes. 1) the bite had to be a laud thing people woud know about it, so they woud knew who Micheal was and that he was responsible for that. 2) He wanted sepreted himself from his past, start a new as somebody else. 3) He was aware off he's father doing and to wanted to escape that (less likley option for me tho). In SL we know that Mike, got some message from he's dad, and he came to search for Elizabeth. To some degree he needed to know what had happend to her. That she went missing in CB Pizza World. Did he know that he's dad had invowment in it? We don't know. I thing not really? William in iniverse never was CAUTGH for those murders, NO ONE KNOW what happend to those kids. They'rs a big chance that Mike didn't know eather. From he's perspective he's dad was searching for he's sister and now he asked him to continue he's serch. Did he know CB was Elizabeth? I don't thing so, if he did he woud go straight to CB and freed her, isntead off working in this place propably searching for clues. Untill CB reveald what happned that day. Amd then he got scooped and somehow he still was alive - propabke then he conected the dots that CB CAN BE Elizabeth. Because if he was alived even ifg he's flesh was roting so Elizabeth coud haunt animatronic that killed her. When he speaks to William he's woice sounds so detached... he holds no emotions towards William. He don't know whats happemd to him, he don't know where he is. He just know what William went missing. He speaks to him not as son who despretly seeks for thruth off what heppend to he's loved ones, but more as somebody who just serch from they're own curiosity. Meybe clousure, to finally close this chapter and move on witch they're lives. We don't know if he was the one who sets frazber fright into flames. WE DON'T know if he knew at that time that William was Springtrap. He was propably in fnaf six tho. So what we know about him from that? Not much really... He maybe likes kids? He keeps childrens drawings in he's office.

He and Henry didn't keep in contact after all that fiasco. Henry admits that he had suspision who was he's "brave volontiree". Did he wanted to stay bechind and burn wich he's familly? WE DON'T KNOW BECAUSE HENRY MADE THE CHOISE FOR MIKE. He literally said that "there was suposed to be way out planed for him but HENRY have fellings that it's not what Mikes wants". And that's it. In loog book we know that Mike is great artist

and that he relate to clara from the show he likes to wach,l because "he notive weird things keeps hapening around here".

Wich sugest that Mike have some suspisions, felling something was wrong. (In fnaf 1 he was fired from messings wich animatronic - maybe he was searching for cluess). Also that he stinks hat can sugest that it's happening after he was scooped.

We know he can be sarcastics. People say that he joke's about he's brother death BUT IF WE READ TEXT ABOVE we see that's a task to "find alternative ways to explain misunderstandings" wich is fancy ways off Freddy's dogings all blame iff some acvinds hapends one off them is that Freddy biten somebody. It's just Mike doing the task and propably reapiding stuff he was taught while working at Freddys.

We know that he wants wacation tho

. And somehow he is importand to SB if he's secret room means anything. (Btw this room drives me CRAZY)
