the fact that when melanie got the poisoned coffee she assumed elias likes it the same way as jon… his little AMUSED confirmation that she was right before he goes “ik youre attempting murder but nice try”
what makes it so interesting for me is that it wasn’t necessary to specify what kind of coffee she brought and why, and it definitely wasn’t necessary to confirm that yes, we do take our coffee the same way, thank you very much. besides, wouldn’t it make more sense for Elias to say that he doesn’t like it and ask Melanie to drink it? so why add this in the first place?
I thought about it a lot, and I don’t know if I’m going somewhere with this, or am I just too obsessed with them, but this little remark could be about Jon’s loss of humanity
why would Melanie assume they like the same type of coffee? well, that’s because they are the same to her. she sees both of them as eye monsters, one of which is arguably worse, but she hates Jon too and thinks it’s his fault that she’s trapped here. they are the same kind of evil for her at that point. they might as well be the same in this for all she cares
and they are. this unconscious assumption immediately gets confirmed by Elias. it’s a tiny off-hand remark, but it shows just how similar they are even in these mundane details
