I doubt Chryssi will be involved, but I could see a little foal in their future given the merchandising and the stories that are available from it. The stories would need to be well thought out in order not to retread the lessons learned in babycakes, but it could be a sweet story.Perhaps we'd see the bags under the eyes of the newly minted parents to contrast the cuteness from a bouncing baby. Perhaps it would be twins as well for an additional Pinkie tie in. Maybe Twilight is visiting (for once the world isn't coming to an end). She tries to spend time with her BBBFF, but he's very busy with the foal. It could be a lesson in feeling abandoned because your sibling has a child, but that they still love Twily very much.

My favorite pony is Applejack. Some may deride her as a background pony, but I think she is a very necessary cog in this friendship machine. She's level headed for the most part and plays Only Sane Mare to a lot of the crazy that goes on. She provides a contrast against the more extreme personality quirks of the mane 6. Sure she's a bit prideful and stubborn from time to time, but I identify with those flaws. I honestly believe and many share my opinion that she is the most stable of the six.(Oh, goodness a pun)

Diamond Tiara is the less sympathetic "villain" Both seem to suffer from a need for attention, It may stem from a lack of attention as a foal or some other void they are trying to fill with attention. Trixie tries to fill that void with power and spectacle or at least the illusion of it. She really wants to transcend the mask and be powerful. She I believe can be reformed at this stage, hence her Great and Apologetic Trixie at the end of Magic Duel. She may be turning it around. Diamond Tiara has the same problem in a way, but she deals with it through bullying others. Trixie bests the other ponies only when they have directly challenged her, though after she has provoked them. Diamond Tiara does it with no provocation whatsoever. I don't really count magic duel against Trixie, because the amulet had a profound effect on her already insecure and outwardly egotistical nature. I think the greatest agent for change with Diamond Tiara is Silver Spoon. If she decides to stand up to her a bit it may unseat some of her precariously built outward egotistical persona. It also may allow for her to make a change and become a better pony.

I suggest that some agent (natural or otherwise) has caused them to have equal cutiemarks. This could be a natural occuring magic force or a deal with the devil in order to resolve some conflict. They'll likely be perfectly content with the situation because they forgot the talent they used to have. Nobody fights, but nobody really lives up to their potential. Something will happen to reverse this effect, and the mane six will have to help them overcome the jealousy they may have held before and accept the differences that once tossed them apart. Bonus points if the agent that gave them equality is also the one that boiled in the strife and is feeding off their missed potential.
