'Percy Jackson' Season 2, Episode 3 Recap: [Spoiler] Is Finally Back!

Welcome to the Andromeda.

When they run into Alison Sims, Percy realizes it's a trap because the daughter of Apollo is one of demigods who was hunting Grover in Percy's vision — and who sided with Luke over the gods. The realization leads to a pretty epic fight where Percy and Annabeth protect each other, watch each other's back, and eventually send Alison overboard.

When Percy and Annabeth are brought to Luke (and Tyson is sent underground), the clear tension between them feels totally earned. Annabeth is still devastated that Luke betrayed camp (and Thalia) and is clearly taken aback when Luke claims she never actually knew Thalia, and that she would be on his side if she were still alive.

Turns out, Luke is on his own quest: to use the Golden Fleece to help restore Kronos and bring an end to Mount Olympus once and for all. But it turns out Percy and Annabeth still have the upper hand; because while Luke put Tyson to work, no one realizes Tyson is making an explosive...until it goes off and our trio can make their escape.

Percy finally learns The Prophecy.

Another super cool detail about this episode is that Percy finally learns about the Great Prophecy: that a child of the Big Three (Zeus, Poseidon, and Hades) will become a weapon on their 16th birthday with the power to bring down Mount Olympus — which means Percy could be a very important chess piece for Kronos.

Luke teases him about the prophecy, but it's clear just how important Percy is.

Clarisse's quest for greatness.

After receiving her own prophecy at the beginning of the episode, Clarisse ends up setting off to find the Fleece on her own — and running into her dad. That's right, Ares is back! And he's recruited an entire army of the undead as her backup, but none of the men take her seriously...until she tells them that if they can succeed in this quest, their lives will be changed for the rest of eternity.
