Dwell on Dreams

I personally can see Dean accidentally calling Jack "Sam" sometimes (y'know, the other kid he raised), maybe when Jack is acting exceptionally childish.

That sounds like a most excellent idea for a poll, tbh. Lol!

Critically, I don't think Sam ever calls Jack by the wrong name because he doesn't get worried or flustered enough about people in general, and he hasn't, you know, really raised anyone before. Tragically, he will accidentally call Dean Jr. "Jack" at some point, leading to a melodramatic blowup when Dean Jr. discovers that Jack was a real person.

Cas doesn't get words wrong, unless he's doing them on purpose. His nicknames for Jack are all saccharinely dated and embarrassing: "Slugger, Sport, Champ, etc."

Dean, though. Dude, yes. Headcanon accepted. Dean calls Jack "Sam" as an insult. When he's being childish or stubborn, when he's not cleaning up after himself (hello, that time Sam tossed the gum wrapper on the floor), or when he breaks something, like the time Jack and Mary accidentally put those knife gouge marks on the library floor.

Jack becomes "mini Mary" when he's eating too much or when he eats undercooked meat (steak n' eggs, bloody). Mary corrects him, "I think you mean, mini you."

In the heat of the moment, Mary goes through the whole list though: "Dean! I mean Sa-I mean Jack, heads up!" During hunts, because of the AU Earth experience, she's more used to fighting with Jack, so she often calls Sam and Dean "Jack" outright. Sam is SO offended about it.

Mary: "Dean! Uh, I mean. Sam." Mary (to Sam during a hunt): "Jack, 3'o clock!"

Cas: Dean! ...Sam. Whatever.

///

Once, in a fit of frustrated anger, Dean bites out that Jack is being "that half-cocked, knee-jerk kind of reckless, just like his dad."

Jack, horrifically wounded, locks himself in his room and refuses to come out.

But Dean meant Cas, not Lucifer.

///

The only time Cas calls Jack Sam is when he mistakes Jack for Sam. One day, Cas is in the library. He's deep in a difficult translation, distracted, not paying much attention to his surroundings. Jack accidentally knocks over something, maybe a chair, to which Cas quips:

"Quiet, Sam."

And it's so cold and biting that Jack is thrown for a loop (he doesn't get to see that side of Cas, like ever).

"Oh. Sorry, Jack. I thought you were Sam. Are you feeling all right? Your balance isn't usually so terrible."

Yeah this would be the most hilarious tbh. And sooo many hurt feelings possibilities too.

Hanging this next to Jody accidentally calling Jack "Owen."
