Dear Joanna,

Don't hit me for calling you that, alright? It's the first time and it's more than likely that it'll be the last time. Besides, I know you could kick my ass, even though you're like, eight feet shorter than me. I could tell from the first time we met you. Kinda got off to a rough start, didn't we? And after a first impression like that, it kinda amazes me that I ended up thinking of you as a little sister.

And I do, really. You're as much a part of my family as Cas or Bobby {...} or even Dean. There's nothing I wouldn't do for you, Jo, and I wish {...} I had more time to do it. I wish we'd had more time back home. But such is life, right? You never were one to let those kinds of things keep you down, which all just goes back to that first impression. A fireball of a woman, unyielding as a mountain and with the bite of a lion. Right off the bat, I knew you were a strong girl and not someone to be messed with. Not that we don't mess with you plenty, but that's just how we show our love.

Leaving you in that store was the farthest thing from easy, Jo, and I can't tell you how much I appreciate being able to spend time with you here in the City. We got a chance to get closer to each other, something we never had back home {...} and now I have a chance to protect you, as much as I know you won't want it.

Things don't end pretty back home, but I promise you, your sacrifices weren't for nothing. And as long as we're still here, we'll keep on fighting side by side, 'cause I know you wouldn't have it any other way.

Love always,

Sam Winchester
