If you don't know I like Sokeefe I do. Not saying Fitzphie is bad. Just saying I like Sokeefe. Respect for if you like Fitzphie. I got a theory of how Sophie likes Fitz more than Keefe.

You guys know how Fitz found Sophie. And elves are so much more handsome and pretty than humans. So, OF COURSE Fitz is gonna be more handsome. He's the first elf Sophie meets. She's gonna think that Fitz is the most beautiful person ever, so instantly she likes him because of his looks. Keefe is also handsome but! Sophie didn't meet him first. Although she says he's handsome sometimes in the books, she always compliments Fitz more on his looks. So Sophie sees Fitz first, he is the first handsome person she's ever met so instantly her reaction is to like him. She sees Keefe 3rd I'm pretty sure, so she's already seen two elves and doesn't think he's more handsome than other elves.

If you don't get what I mean, comment and I'll try and tell you. Also comment if you have another theory or agree or disagree.
