If I had a coin every time I've heard this, now I would own Hasbro.I got fed up that they say that when Twilight turned into alicorn, say they also became immortal and someday abandon her friends. It seems ridiculous that that all princesses or alicorns should be immortal, perhaps princesses like Celestia or Luna if, for they are like goddesses, but i dont think that should be also be immortal princesses like Twilight or Cadence, as they were normal ponies before.Also, when I told him the same thing to , he told me that as he read through the Twitter of some of the people who work in the series (including Meghan McCarthy) and have said very clearly that immortality is not going to happen to Twilight and she will never leave her friends.
