The wedding of Fancy Pants and Fleur certainly doesn't sound like as huge a deal as a princess wedding does. Everypony was supposed to be too distracted by the princess wedding to notice the changeling invasion. I don't think it would have worked with lesser characters.>>472805
Obviously not, parents are parents, not friends. She also has never called her parents her friends while she has called Cadence one.
I do admit this isn't the perfect argument and I don't think I can completely convince anyone it invalidates "I used to wonder what friendship could be". However, I do feel it significantly lessens the impact of Twilight actually making friends which I feel is supposed to be an important turning point in her life. It might not be technically wrong but it feels wrong.
Also I'd like to point out the scene where Shining saw Twilight off when she left for Ponyville. It certainly ties this nicely to this thread's topic, retcons…>>472808
Yup. I wouldn't say it directly contradicts anything previously established, mostly because they never did much with Luna and Celestia, but we certainly were led to believe they were the only two. Also the whole night and day thing really only works with two alicorns. I might
have been okay with Cadence being an alicorn had they bothered to explain alicorns to us, give some exposition or anything. But no, so far we have absolutely nothing.
