Eileen had passed away and it was just Tobias left there to take care of Severus at the age of 3, Tobias was never treated well growing up so he would go into rages especially when drunk and not be able to care for his son. So one night while on one of his drunken binges he throws together a box with his son's clothing a few toys a blanket and tapes his son's name to the box and starts to carry the box and his son to the nearby orphanage, he leaves the box there and his son inside of the box and knocks on the door and leaves passing out in some alleyway with his alcohol bottle in his hand, the year was 1963 when all of this took place

Tobias: in his sleep has a nightmare of his past dad I'm not weak, I can do better, I promise

Meanwhile some nuns had found Severus outside in the cold inside a box with a few of his things, they take him inside and warm him up feed him and find him a bed to sleep in
