A few facts to establish, is that Luna and Celestia are born alicorns while Cadance and Twilight are ascended alicorns. This means that at a certain level they are different, and I argue in this case that the latter two do not have the longevity of the royal sisters.Second, Meghan McCarthy has officially stated that Twilight will not outlive her friends. Now admittedly, how this will play out can be up for argument. Still, I feel not outliving her friends is pretty straightforward, especially since the question asked is whether or not Twilight was immortal.
