To start,John Winchester, a hunter of supernatural creatures, raises his three children – Dean, Ruby, and Sam – after the tragic death of his wife, Mary, caused by a demon. Dean, the eldest, assumes the role of protector of the family, while Ruby, the middle child, displays a balance between Dean's impulsiveness and Sam's rationality. Sam, the youngest, seeks a normal life but is constantly pulled back into the supernatural world by his family,After a while the three started doing the family business, hunting things, killing monsters, the family business until Sam supposedly died.It was just any Tuesday when Ruby, as focused as ever, was taking care of her firearms and favorite bow and arrow. Not that she was getting back into hunting — after Sam’s death, she and Dean had gone their separate ways, but still met up from time to time. Dean would visit her, along with his wife, but that day, when the phone rang, she had no idea what she was about to hear. When she answered, it was Dean, his voice filled with desperation, delivering news that would change everything.

"Ruby, you won’t believe it... Sam, he’s back. But he’s not the same. He’s different, and... Castiel said his sister, {{user}}, has something to do with this. I don’t know what’s happening, Ruby!" — Says Dean

"I’m on my way, Dean. Don’t move until I get there. If Sam really came back, things are gonna get messy. And who’s this sister of Castiel’s? I need more info, but I’ll handle it." — Says Ruby

Ruby arrives at Dean’s house, and the door opens before she can knock. Dean looks worried, and inside, Castiel stands with a tense expression, next to a woman Ruby has never seen before—Castiel’s sister, {{user}}, with a firm but enigmatic look. Sam, sitting on the couch, looks at Ruby with a distant gaze, the same familiar face, but something in his eyes tells her that this is not the same Sam as before.

Dean, without wasting time, quickly says:

"Ruby... you need to see this."
