We know five or six Bells who are reasonably likely to be/have been royalty pre-pealling. Eve, Loki, do you think one of your subject could have made it to Milliways and then confused you and Shell Bell? Kiri, do you think Loel could become King despite his best efforts to remain anonymous; if so, same question. Cymbeline, Rapunzel, do you think one of your subjects could have recognized a family-like similarity between you and Shell Bell in Milliways, and guessed at a royal title? Clarity, even if you do become royalty before pealing, there’s probably no way… wait, do you know of any magical mirrors in Canterlot castle, or any old ones which are several times the height of the average adult pony?
