I don't know if anyone noticed this but when springtrap was making a new springtrap when the second one came alive it was not William in the second body he was still in the original one because if he was in the second body the first body would have stopped moving the second springtrap was not William and when the second killed the first that thing was released from the ties that bound it to the first if the second was also williamthat thing would still be bound
I have an explanation for the second question, but not the first. The second Springtrap suit has the soul of the SWAT guy that got springlocked, so that's why he attacked and killed William.
Honestly Gacha life players have to stop since because its putting a bad view on them to because when kids see the acutaly animation they will think its not even scary but in reality its acutally dark kids will put a bad view on sonar just like dababy when kids hear lets go they will make fun of them but in reality the rapper has real things that are terrifying its gonna happen to sonar if the gacha life community continues this also goes with every else animator and everyone else this is why gacha life is ruinkng every single video on RU-vid Dont consider this as RU-vid also you can get copy right striked if you dont ask the owner of the original video just letting you know for saftey as again dont take it as hate.
