The goal is to finish this in one more comic. The turning point (possibly) for Zephyr has been realized and seen. But will he follow through or have lapses in the future? What will he do about his friends and family? So there is much to do there, but all that can be one-off things.
By the way, the "room service" pony is based on a real character from the series known as Sparkleworks, whom I think only appears in the MLP cartoon once maybe? I'm not 100% sure.
