I’ve been rewatching season one and in the episode Dreamy, at the Miner’s day festival, Astrid/Nova is talking to 2 other nuns-one of which is blonde. Seeing as how all the fairies we have seen so far are all nuns, could the blonde nun be Tinkerbell?
Also, in Skin Deep, when Regina went to see Belle in the mental ward, she only referred to Belle as “her”. Could it be Belle was the only female patient on the ward at the time or had Regina visited Belle enough times previously for the nurse to automatically know who Regina was referring to?
