Shoulda taken the deal, my man. You're dealing with atrocious folks with no moral standards besides apparently looking at a corpse's panties.
....So, uh...did No.6 and Alice just get married? Engaged? I mean, more power to them if they did. I'm just not used to relationship upgrades happening like that.
I'm still a Grimm fan myself, but Alice is acceptable. Dependable wife is always a good choice.
Rose is too much of a child/beast and Snow is actually worse than Aqua from what I can see, so they were never candidates. Astaroth can shove it because fuck tsundere shticks.
