From @neonthebright:
Oh, goodness, I don’t think we ever even thought about this! Felicia is usually human, so I think she’d still be a human in those AUs. She’d definitely annoy the crap out of Colfax because she just doesn’t shut up about these fairies that he knows nothing about. Really, woman, just leave the poor man alone.
From @creatorofuniverses:
Let’s just throw Felicia at everything, why not. That’s what we do all the time always. XD It would make things extra ridiculous. With her being the same size or smaller than everybody else I can’t see her doing too much damage. Mostly she’d probably just be aggravating, maybe even moreso to the humans. For giant!Sawyer, at least, he’d just quietly dislike her. Unless, of course, she upset any of his human friends. Then he’d dump her in the next county over. XD
