So here's what I'm thinking for the first S-Link: https://pastebin.com/0m29tzhE
The idea I'm trying to get across is that this is sort of a transitional S-Link, in that Twilight still retains a lot of herself and also these new, slightly wild, feelings that she doesn't know what to do with. If there's enough push for it, it's possible to keep some of the book-nerd qualities, but tone them down in favor of more 'fun' things.
I was also looking to have her language alter a bit during this period from the other S-Link, to show a continued change from the character, so let me know if that's too much, too soft, or just enough. And any other input is appreciated as well.
