It bugs me how many people prefers to deal with Twilight’s “inmortality”, while that time, Twilight can just find ways to become mortal again.
I found this comic, and there is a page where Discord provokes Twilight to enter into a mental crisis because the inmortality. And the first idea that comes to Twilight’s mind is if there is a chance to turn her friends and everyone into inmortals
…Twilight, instead of doing that, why dont you care to turn into a mortal by yourself? Specially Discord.
