Niiiiice, Yumikuri is always welcomed in my book.
On a sidenote: I have a feeling that Ymir will eventually die during the story. I mean Christa (Historia, whatever) just became... umm... fuck I forgot how to make a spoiler tag XD Anyway, she's significant to the stoy, so it would be weird to dispose her and since Isayama likes to get rid of characters... I can't see any happy ending for them, which is sad as fuck.
