If Emilia is Satella then wouldn't it be a Plothole that she killed Emilia after Subaru told Emilia about RbD?
I mean if she killed herself before she became Satella and granted Subaru RbD Subaru shouldn't be able to use RbD thus the Witch Cult would've never existed but in that Timeline it still exists.
Maybe that's a little to much interpretation into that one scene but it's either a Plothole or it disproves the Satella=Emilia theory
