Ah, nope! If that other answer was confusing, it just means that Jacob from his canon story would have been a better option to meet than the Brothers Lost version of him! If he’s met little guys before, Jacob learns very quickly to treat them like people. He’s already learned not to keep pie from Dean, after all! There’s hope for him yet, like there always is.
Just for clarity, in every AU except for Brothers Apart that we have created so far, Jacob and Bowman have not met each other at the time of the first story in each AU.
If they had, Bowman would give this Jacob a good bopping for sticking Dean in a coffee pot. Bowman’s Jake knows better than to treat smols like that. Silly boy.
