I Can’t Promise That

After Starlight takes a hit for Twilight, Twilight practically begs Starlight to not let herself do that ever again. Starlight can’t make such promises.

When King Sombra attacked Equestria, Starlight ended up taking a blast for Twilight so she wouldn’t have to. After the madness ends, Twilight begs Starlight to never do that again. Starlight wishes she could keep that promise but she knows it’s impossible.
