My copy of Fates hasn't arrived yet, but from what I've seen, Silas definitely is a cutie. I considered marrying him awhile back, but eh...there are too many good options in my opinion, in Nohr, at least. Though I do think I'll be marrying him in my first run. (Plus, Sophie is pretty cute in my opinion, so...) But honestly it's just personal preference here. I'm also not too keen on marrying the siblings either.
