Emily is pronounced similar to Amelie, so maybe it's Lena's way to cope with the fact that she couldn't be with Amelie. Or maybe I'm just still clinging too hard on the (sadly sinking) ship I've been sailing with for the last couple of months
I might just be my multishipping tendencies speaking, but I kinda got the feeling Karin liked Yuuna as well. Oh, well, nice to see this (poor Tougou in the background, tho)
