Let's Breakdown that ‘Percy Jackson and the Olympians’ Season 2 Finale

• The quest to bring the golden fleece back to Camp Half-Blood succeeds in season 2 of Percy Jackson and the Olympains, but only after a full-scale monster invasion...
• Luke crosses a point of no return, proving he’s no longer just a disgruntled demigod but a true enemy.
• Thalia’s resurrection brings a Zeus-sized twist.

After seven episodes of mythical mayhem and tested friendships, the season 2 finale of Percy Jackson and the Olympians ended with a twist worthy of the gods.

What started as a simple “grab the golden fleece and save Camp Half-Blood” quest quickly devolved into a few near-death experiences and a slew of messy betrayals. This whole being a hero thing is turning out to be a lot harder than the prophecy made it sound, huh?

In the end, Camp Half-Blood was still standing, but the vibes are officially much, much darker. The Sea of Monsters may be behind us, but the consequences definitely aren’t. A lot went down, so let’s dissect exactly what happened in the season 2 finale.

Does everyone make it back to Camp Half-Blood?

After escaping Luke's ship, Percy, Annabeth, Grover, and Tyson hitch a ride back to camp. Not in a super cool demigod-like way, but thanks to Percy's mom and her little blue sedan. (Whatever works, right?) During the drive, Percy keeps going over the prophecy in his head—that a child of the big three gods (Zeus, Poseidon, and Hades) will either save the gods or be their downfall.

As they get close to Camp Half-Blood, they see Blackjack, the pegasus that Clarisse rode back to camp, standing in the middle of the road with no Clarisse in sight. Percy gets out to see what's up and learns that there are monsters nearby and that Clarisse (who's in possession of the golden fleece, in case you forgot) took off on foot. Percy tells his mom to get a safe distance away from camp, and the kids all head off to find Clarisse.

How are the monsters getting into camp?

More and more monsters have been making their way into the camp, and just as Tantalus is trying to pretend that that isn't happening—deciding that trying to clean up the chariot racetrack is much more important—he gets hit and killed by an incoming fireball.

So how do these monsters keep getting in? Well, when Luke and all of his team-Kronus goons show up at camp by the truckload, Percy and crew overhear them talking. Turns out there's a traitorous team on the inside that's been helping let the monsters in. And the primary culprit? Chris.

Chris, while out on patrol (supposedly to defend the camp), finds Clarisse but turns on her pretty quickly to get the golden fleece. Just as it seems like he's about to win, Annabeth and Grover come wizzing by in a chariot, Clarisse hops on, and they whip out of there.

Meanwhile, Luke has made his way inside the camp and lifts the barrier to let more monsters in. He's on a mission to find the golden fleece and bring it to Thalia's tree to heal her and bring her back.

But why does Luke want to save Thalia?

The fact that Luke and Thalia are friends, and that he thought she was all but dead, might be part of it, but he's also got some selfish reasons too. Luke believes the prophecy isn't about Percy at all–it's about Thalia. In his mind, she'll fight on the side of Kronos and help take down the Olympians, ending their reign of unfair treatment of demigods.

How does the battle at Camp Half-Blood go down?

After Luke lifts the barrier to let more monsters in, Percy, Tyson, and all of Camp Half-Blood make their way over to defend their camp. Fighting starts, with Luke and Percy going head-to-head. Just as it looks like Luke is about to deal Percy a fatal blow, Tyson steps in just in the nick of time (phewf!) and saves him.

Things aren't looking so good for Luke's crew, so Allison and a few of Luke's army start trying to chop down Thalia's tree (it's what's powering the barrier). Clarisse is having none of that and throws a javelin with the golden fleece attached to it into the tree, and it starts the healing process. And then, BOOM, Thalia reappears in human form with a big strike of lightning that knocks her and Percy out. In a dream, Percy sees his dad, Poseidon, who warns him that war is inevitable.

Cut to three days later, Percy wakes up in the hospital while Thalia is still passed out in the next bed over. While he was out, Chiron was reinstated at the camp, but his grand return comes with some bad news about what really went down when Zeus turned Thalia into a tree.

So what really happened to Thalia?

The story, as everyone knows it, is that Zeus turned Thalia into a tree to spare her life after she was fatally injured by the Furies. Welp, turns out Chiron was there and saw the whole thing go down, and that's not what actually happened.

The Furies didn't attack Thalia at all. They brought her a message from Hades–something that would drive a wedge between her and Zeus. Zeus, ofc, was pissed tf off, since he was banking on Thalia fighting for him in the coming war. She tells him she doesn't want to be his weapon, and Zeus, out of anger, turns her into a tree.

Back in present day, Thalia wakes up and makes her way to the gang. She sees Annabeth and recognizes her, even though six years have passed since Thalia last saw her. She then quickly asks where Luke is, which likely only made Percy even more worried about who Thalia is going to side with when it comes down to it: them or Luke?
