After so long and all the confusing news around the episode itself, we've finally gotten a synopsis for The Fault in Our Cutie Marks!
Looks like we can expect an interesting adventure with this one. Check on after the break for the full synopsis.
Thanks Iva for sending it in.
Some lore (along with Gabby's name) were revealed some time back that pertains to this episode that can be found here. And since people have been asking, the little gryphon in this image isn't Gabby, but a background gryphon in S5E8.
