Is it better to have loved and lost? Lauren, Bo, Tamsin, and Dyson each must deal with the painful emotions associated with having ones heart broken. This close to the end we still don't know Hades' end game, and we're introduced to yet another god. And he's the ugly one?
Through a series of flashbacks, we're introduced to Tamsin's teenaged backstory at Valkyrie school under the tutelage of Freya and later Acacia. The plan to return Hades to Tartarus is complicated by the fact that his desire to assemble an army is now out in the open. Will Tamsin lead the armies of Hell? What is Jack really up to? Will Dr. Lewis eventually be able to return Evony to her greatness as The Morrigan?
The effects of Lauren's science experiment come to light, but the implications remain clouded as we await the fae colony reaction. Alicia discovers Dyson's secret, and Kenzie returns to help Bo acquire a painting needed to send Hades back to Tartarus.
Having released her father Hades from the music box, Bo must now work with him as the fae try to prevent Zeus from carrying out his end-of-the-world scenario. Moral and ethical decisions abound in this episode as Dyson must decide how to tell Alicia the truth about her husband, while Lauren's latest lab project presents far reaching consequences.
