Yeah you're pretty spot on with Kris. I made mine a girl in my FE12 playthrough, at the end of the final chapter Marth told her "Please stay with me. You're my other half, my true friend" with poor Caeda standing right there lol...that shit was messed up. Your fiancée (who also happens to be one of my fav FE girls) did not carry my ass through 2 games just so you could do her dirty like that, Marth. I haven't played FE3 but from what I've heard, Kris steals some key story moments from Jagen and a couple others too. FE12 also dedicates half of the support convos to Kris; it's better than FE11's total lack of supports, but still not ideal...and the sad thing is that even though I've read a good deal of them, the only thing I could tell you about Kris is that she likes training.

Also agreed on F!Robin, she's the fucking best. Her supports are all hits and I love how she has a bit of an attitude compared to her male self (also she rocks that outfit better than him tbh). Her, Chrom and Lucina are just the coolest and the Marth No More/Chapter 21/Future Past drama is just amazing with F!Robin as Lucina's mom.
