When Walter crossed over and took Peter, one of the repercussions that he never knew about, was that he also started a war between the fairies and the alt-fairies.
This is one of the weirder ideas I’ve had, I admit… but I just loved how the green fairy in 5×09 “Black Blotter” met the red fairy. Yet, it stands to reason that if Walter tore apart the fabric of space and time, it probably impacted Fairyland as well. So, all was not well in the old timeline.
The lighting in this is kind of… nonspecific. Also: it’s so much easier to draw naked fairies.
That is all.
