Despite their detached relationship, Thorax never gave up on his brother. With Pharynx now transformed, his cold demeanor has begun to thaw, and so Thorax is presented with something he's never had, before - an interactive big brother.
Atop Chrysalis's decimated hive, King Thorax confronts his former peers. When their discussions are interrupted by a confused and scared changeling nymph, Thorax demonstrates the power of sharing love between changelings.
Embracing the power to share love rather than steal it, the changelings work to reinvent themselves and their kingdom while Thorax seeks to introduce a more peaceful hive to Equestria.
