Well, I guess Hell confirmed for canon (at least, in Japanese Equestria XD)
 
For reference, the original English line (or part of the line that I felt was relevant for comparison purposes) was: “…but if he’s here, then all of the evil creatures that have been imprisoned there could escape…”
 
And also, I was inspired by >>450299, but I have neither the time nor the patience to make something as elaborate as that, haha
 
Thanks to Choco Rei-chan for the subs; they’re always great!
