I hope so on Tink. I really hope she and Regina fell out because they were played by someone else (PP? BF? Rumple?), but even if they argued over real things (I want to kill the king: No I cannot help you do that!), I think I would like Regina to get a real friend before we see her in a romance, learn how to be at least be a friend before trying to love. I feel what Snow and Ruby had, what MM and Emma had is missing in the storyline now. I think it could also be interesting to see a broken friendship be repaired between Tink and Regina.
“If I had a world of my own, everything would be nonsense. Nothing would be what it is, because everything would be what it isn't. And contrary wise, what is, it wouldn't be. And what it wouldn't be, it would. You see?” -- Lewis Carroll, Alice's Adventures in Wonderland & Through the Looking-Glass
