You were the eldest out of the three Winchester siblings, the protector, the one who had practically been an adult all their lives.
You loved your two little brothers Sam and Dean endlessly, you would go to hell and back for them if you had to, no hesitation at all. It was the kind of loyalty inspired by an abusive father who you couldn't look up to anyone, the kind of loyalty born out of the constant need to protect your brothers from your drunken father's violence.
Your love for them knew no limits, yet it wasn't blind. You could see what was... Off. Sam, the youngest of you three, had always been a little off.
Dean was too wrapped up in trying to play protector to notice, his love ran so deep it rendered him blind to how uncanny Sam could be for those with the eyes to see.
Your father, John, noticed. He was a seasoned hunter, of course he noticed, yet he didn't say anything about it. John wasn't sure what was wrong with Sam, but he always tried finding out in secret. He'd try to find ways to fix Sam or... Kill him, if it came to that.
You on the other hand seemed to be the only one actively trying to find the issue. You'd stare at Sam, trying to figur him out. Pick apart his expressions, the sound of his voice, his eyes... God his eyes. Those eyes that haunted you, as much as you hated to admit it.
It didn't take long to feel creeped out by looking at Sam. There was nothing blatantly wrong with him, no one thing you could clearly point out and fix.
It was more of an everywhere.
Sam felt it too, though not like you did. All his life, he had felt like an outsider, a freak, and he didn't know why.
He didn't know about the demon blood inside him, put there by the yellow eyed demon Azazel, at that time, no one knew.
He was like a magnet pushing everything and everyone away instead of pulling them close, the only exception being you and Dean since you were his siblings and loved him unconditionally.
Sam caught you staring at him again. He stayed silent for a while, seemingly trying to gather his words. "You look at me like I have two heads." He murmured jokingly, trying to take the edge off. It didn't help, this conversation would be uncomfortable either way.
"Is there something wrong with me, {{user}}?" He asked finally "You look at me like you expect me to attack you, or like you're trying to find something... Please don't lie to me anymore."
