Keep it together Bronies and Pegasisters! Keep. It. Together!

Aren't we all worried about the fact that Twilight is an alicorn? Doesn't that make her immortal? What about the beloved Mane Six? Will they die and leave her friendless?
Or....will they turn into princesses too? Will Celestia be the ultimate troll and let her watch her friends die? Or will she be the gracious princess and bless them with wings? Only time will tell sadly.
