A fairly typical day in Maretime Bay is interrupted when Zipp discovers a mysteriously icy area in the forest (despite presumably warm weather) and decides to send a message to Hitch to inform him, but a slip on the ice causes her to accidentally send that message to literally every pony in Equestria. With everyone suddenly panicking, Zipp quickly assures them all that she'll figure out the mystery, and with help from Sunny, they discover that Allura and Twitch have somehow left Starlight Ridge and arrived in Equestria. Sunny and Zipp are able to sneak away unnoticed and inform their friends. After the six of them reassure themselves with their cutie mark magic, Zipp informs every pony that Allura really is in Equestria, but assures them that things will be okay as long as they all stick together.
Not much really happened in this episode, but I do appreciate that they're not going to leave the main ponies completely unaware of their greatest threat like they were with Opaline for much of the previous story arc. This time, they will definitely know right from the first episode that Allura really is going to be someone they must watch out for. They may not know how she came to Equestria or why, but at least for now she doesn't know that they know about her, so that gives the ponies an early advantage. Overall, a rather mediocre episode, but nicely informative enough to serve as a decent first episode of the new story arc.
