While Claire's team are looking for Krohnisfere at Hong Kong, Jim's team are looking for Skrael Titan at the Greenland where they're using the flying castle to fly through the the cold wind.

Jim: Krel's coordinates show we should be on top of it.

YN: Maybe his numbers are off.

Aja: What would they be on?

Toby: Iceberg!

They see the they're moving towards the iceberg close until it suddenly moves on its own.

Jim: That's no iceberg!

YN: Steer the castle!

Barbara and Strickler try to steer it but it was too heavy until Aja jumps in and grabs the wheel.

Aja: I've got this.

The castle steered away from the ice where YN earthbend to create a wall to protect them from the ice shards.

YN: I'm going in!

YN jumps and grabs on the ice titan with the claws on his gauntlet thanks to his metal bending. He starts climbing while the others manage to get to a safe distance from it.

Jim: I hope the others are doing better.

Meanwhile at Brazil, possessed Nari is marching out of the through the forest with her titan while Douxie team are catching up to the titan where UN is using his earthbending to catch up, Douxies riding on Aarg back, and Nomura jumping from one tree after another.

Douxie: Aarg, we're catching up!

Aarg tries his best to avoid any sunlight as minimal as possible.

Nomura: Keep on with its shadow!

UN: Go for its leg, its the only way getting up there.

Douxie: There, there. Take me there.

Aarg grab and throws Douxie to the leg but Douxie was unable to reach.

Douxie: Oh, fuzzbuckets!

Fortunately Nomura caught him and throw him up so he doesn't have to climb all the way up.

Douxie: Oh, made it.

Suddenly the titan vines grabs him and toss him off the ride. Fortunately Aarg caught him just in time.

Nomura: Urgh, sloppy.

UN: Go on without us, we'll try to slow it down!

Nomura nods and climbs her way up. Back at the Greenland. YN is still climbing his way up to Skrael while the castle is following the titan.

Jim: Man the cannons.

Strickler and Aja are loading the cannons while Toby tries to help, but the cannon ball were too heavy for him. Once loaded, they wait for Jim's signal to fire.

Jim: Hold...Hold....Fire!

The cannons fire and successfully hits the titan which seems to hurt Skrael as well since he's link to the titan.

Jim: Fire again!

They fire again, but it wasn't enough to stop the titan. This made Aja leave before Toby ask.

Toby: Where are you going?

Aja: To heat things up.

Back in Brazil, Nomura tries to make her way to Nari. But the titan keeps moving which made her having trouble with her balance.

UN: Douxie, help me slow down the titan!

Douxie: (Nods.) Tenebrius Excilium.

Douxie uses his magic to hold the titan legs for UN who got in the front.

UN: That's it, keep it like that.

UN uses his earthbending to sink the titans legs to the ground. Hoping it'll hold for Nomura to get closer.

At Greenland, Aja hop on her ship and fly towards the ice Titan and starts shooting it down while evading its attack. YN did manage to reach its shoulder, but with the titan moving its arms, he's having trouble to keeping himself balanced while Jim gets an idea.

Jim: Can you get me on that?

Strickler: In this weather? My wings would freeze. We'd fall like a rock.

They glances at the harpoon and gets an alternative idea.

Strickler: Then again, flying is overrated.

Barbara: Jim.

Jim: I know, Mom. I'll be careful.

Strickler man the harpoon and takes aim.

Strickler: Angels and ministers of grace,
defend us.

He fired the harpoon with cable and hits the titan for Jim to cross as he's holding a belt full of explosives.

Strickler: Careful, Young Atlas. That's a lot of explosives.

Jim: That's the point, isn't it?

Jim uses the belt to slide like a zip line. But the titan pulls the cable where it got too tight for Jim to sliding out of control.

Barbara: No. Jim!

She and Strickler take the wheel and pull to make the castle pull back to slow down the titan with everything its got until the engines dies and the castle fall.

Toby: We're gonna need a bigger castle.

The harpoon couldn't hold as it got detached from the than.

Jim: No, no, no.

Once it got detached, Jim falls down.

Barbara: No, no. Jim!

Without hesitation, YN jumps off and dive down to grab Jim before he fired his own grappling hook to the titan.

YN: I got you, bro!

Jim: Get me get closer to the head.

YN: Hold tight. This is gonna be rough!

In Brazil, Nomura reach to the head as possessed Nari is aware of her and uses the vines to catch her. She was about to drag Nomura to the sunlight as UN notice it.

UN: Nomura!

Without a moment to waste, he slam both his fist to the front of the left leg as it crumbles down where the titan fell on its knee. Giving UN an open to uses his earthbending to jump high enough to reach Nomura.

Nomura: UN, catch!

Nomura toss one of her blade at UN which he caught it and slice one of the vines to let Nomura cut her way out. Once free, he caught her and landed safely on the shade.

Nomura: That was too close.

The titan then recovers and moves onwards.

UN: No, we failed to stop Nari...

Back in Greenland, YN holds on the cable and runs on the ice before jump to make a swing back to the Titans head.

YN: We only got one shot at this, Jim.

Jim: Then let's make it count!

Once they got close enough to its head, Jim throws the explosives before YN covers him to shield him from the explosion the detonated as well as shielding him from the fall. The titan fell as YN notice the ground is crumbling. Without a moment, he threw Jim away before YN sinks down into the water.

Jim: YN!

Jim was about to save his friend, but Strickler stops him from going in the water.

Strickler: Don't! The water will freeze you.

Jim: I can't leave him!

Strickler: Jim...I'm sorry.

Jim: No, YN...

Aja ship landed near and she got off where she notice YN fell in the water.

Aja: Oh no...

Suddenly something pierce through the ice and it reveal a hand and they notice YN is trying to climb his way out.

Jim: Help me get him out of there!

The three helps him out of the water for YN to breathe air which he somehow isn't shivering too much.

Jim: YN? how did you survived?

YN: I asked Douxie to enchant my armor to keep it hot in case we needed to get close. It resisted the cold but not for long. Can't believe it paid off.

Aja: Well, the armor does feel warm.

Aja hugs him to stay warm.

Aja: But I'm glad you're alive.

YN: So the titan. Did we get it?

Before any of them could answer, the Titan recreated itself and continue onward.

Jim: Impossible...!

Strickler: We can't go after it anymore now that the engines are down.

Jim: Let's regroup back to the castle and come up with a plan.

Everybody agreed and head back to the castle while Barbara is checking up on YN after he almost died twice.

YN: I said I'm fine. Just a few bruises.

Barbara: Even with that armor, that fall could've injured you badly.

YN: I'm not gonna let that stop me from stopping the Titans.

Jim: I shouldn't let you helped. You almost died twice.

YN: We've been through a lot Jim. So at this point, I'm not giving up until the end. (Sigh.) Too bad I couldn't use lava bending against the titan. It'd be our best advantage against the ice titan.

Jim: We'll find another way.

Barbara: OK, but at least keep an eye on each other.

Jim: We will.

Toby: Come on, guys, we have to go.

Jim: Go? Where?

Toby: Hong Kong. We've lost contact with Claire.

Strickler: You four should go. If the TrollDragons found them, then they'll be in trouble getting out. Barbara and I will contact the others who are stopping Nari. 

YN: We'll get them out of there. One way or another.

Barbara holds Jim hands.

Barbara: We never give up.

Jim: Ever.

The four head to Aja ship and fly off to Hong Kong. Meanwhile with Claire's team, the trollDragons are taking team Claire to Zong-shi who chuckles as he knews they're coming thanks to the Krohnisfere.

Zong-Shi: Charlemagne, I never expected to see you return here.

Zong-Shi: Old foe.

Charlie: Look at me, you blind fool.

Zong-Shi: I am looking! I am always looking. You are an old fool, seeking to take that which is mine. Mine, you hear? And your hide will hang here as my trophy.

Blinky: It's all so futile, you see? No one can see the future coming.

Zong-Shi: I see more than you could know. (Chuckles.)

Charlie: You demon!

The TrollDragons use their weapons to keep the dragon down.

Zong-Shi: And as for your fleshy friend. Your armor, I shall wear it like an amulet.

Claire: Ew!

Unbeknownst to them, Archie is sneaking his way close to Zong-Shi until he saw they're holding his friends.

Archie: Enough of this.

Archie jumps in and turns into his dragon form where he starts blasting fire at the TrollDragons.

Charlie: What are you doing?

Archie: What we came here to do.

Charlie: (Smiles.) That's my boy.

Archie: Claire!

Archie distracts the TrollDragon to give Claire a chance to snatch the weapon and free herself with it before she swings it to one of the TrollDragons. She holds the weapon and swing it at Blinky.

Blinky: Mistress Claire, no, no, no!

However, this was meant to free Blinky from the cuffs.

Blinky: Yes, I'm free!

Zong-Shi glances at the sphere where he sees the seconds future ahead.

Zong-Shi: My sphere!

Archie snatches the sphere from Zong-Shi and tosses it away before he got caught by Zong-Shi.

Zong-Shi: My sphere!

They notice its rolling towarda the edge.

Blinky: Great gruesome!

Blinky goes after it while Charlie freed himself from the TrollDragons.

Charlie: Unhand my son, you demon!

Zong-Shi: Give it back to me! I must see what will happen!

Archie turns into a fish which slipped out of Zong-Shi grasp which surprised him before Archie turns back into a dragon.

Archie: Bet you didn't see that coming.

Blinky chase after the Krohnisfere until it fell off the cliff. Luckily Archie fly down and catches it.

Claire: We got it. Let's go!

Now that they got it, they escape the palace and run with the sphere.

Zong-Shi: After them, you fools!

All that's left is to escape the lair. But little did they know, things are about to get heat up in Hong Kong
