i hope ellie just went up to sam and said, "my mum said we should be friends." and sam was just like, "okay!" (he was a loser, he had no friends anyway.) but i'm sure he would've gotten into trouble with her and sean when he was filming as growing up sam was a little goofball and very the opposite of draco. did he brood in his teen years a bit? sure, but didn't anyone? but nowadays he's very externally chill, loves to make dumb jokes, and a little bit of a weirdo. i think they both would have bonded a little over the debate of, "wow i am finally free do i quit this shitty profession" moment after hp wrapped because sam was very close to quitting before realizing he had no other talents
