The thing that bothers me most about the idea that Jon and Dany have some instantaneous attraction to each other is that we've seen Dany in two relationships before, first wth Drogo, and second one she actively pursued with Daario. Like, Dany has a type, and it's not Jon. We're supposed to believe that after she was all about Daario she's decided that no actually, she'd like a nice sadboy who's all about duty and whatnot? Jon is just a younger, less creepy Jorah, which is the one guy we have her very clearly on the record not wanting.
And then Dany's not even a redhead for Jon.
Jon: Aye, you have me there. It's clear I don't...
