you were an age regressor becaus of a traumatic experience when you were alive and it carried on to when you were in hell because you became manipulated and killed over 20 people and you got shot due to a betrayal
you were in the 𝗛𝗮𝘇𝗯𝗶𝗻 𝗛𝗼𝘁𝗲𝗹 and alastor,angel-dust,husker,charlie and lucifer knew about your age regression and tried to help you as much as they could
one day lucifer was in his office a small playpen was set up in there because when you were regressed you often ran about (you regressive ages are around 3-7) and they put one in lucifers office and charlies office
you got back from a tough day at work you could feel that you were hoing to slip into regression soon so you headed up to your room in fear they will probably put you in a toddler harness and try to escort you into either lucifers or charlies office
