Whilst Myotismon foils the escape attempt led by Sora, Joe and T.K. find their own way past Myotismon's fog barrier, and Phantomon discovers Kari's location.
Lillymon fails to defeat Myotismon, and has to be taken away by Birdramon who flees with Sora. Meanwhile, Tai decides that he must help the others, leaving Kari with Matt, and Izzy, back in his bedroom, succeeds in setting up a Digital Barrier against the Bakemon, then going off to investigate the source of Myotismon's fog. T.K. runs into Joe at the harbour across the river, and Gomamon digivolves into Ikkakumon to take them to the other side. Tai and Sora run into each other, Tai tells her where to find Matt and they split up again so Tai can get to the convention center. Joe and T.K. soon run into MegaSeadramon, who attacks them and sends Joe and T.K. flying into the water. When Joe sacrifices himself to keep T.K. afloat, his Crest of Reliability glows, and Ikkakumon becomes Zudomon, who rescues Joe and T.K. and defeats MegaSeadramon, before finding Wizardmon in the water, holding Kari's tag and crest. At the communications tower, Izzy runs into Matt's dad, while Phantomon has followed Birdramon to Kari's location, where she gives herself up in order to spare the others' lives.

| Special Move|
|Patamon: "I knew this was too easy. That's MegaSeadramon. The regular old Seadramon was bad enough, but compared to this fully digivolved version, it was just an angry guppy."|

|Patamon: "Don't worry, he's one of ours. That's Zudomon—he's the fully digivolved version of Ikkakumon. I was wondering when he'd finally show up."|
| Special Move|
|Phantomon: "...And here's the second member of our tag team, Snimon: a deadly preying mantis Digimon, which is so appropriate because you're all about to become his prey."|
(Number indicates order of occurrence.)
"Don't you worry. I'm gonna bring Mom and Dad back home safe and sound, and your little buddy Gatomon, too."
- —Tai reassures his guilt-ridden little sister.
"I told Dad I need a quicker modem!"
- —Izzy struggles to get the digital barrier up and running.
"Oops. Well, now that you know I can talk, my name's Tentomon. Pleased to make your acquaintance."
- —Tentomon blows the secret to Izzy's parents.
"I was in T.K.'s wood working class at summer camp! He nearly cut off one of my fingers, but that's a whole different story! I won't go into it right now!"
- —Joe giving T.K.'s mother a little too much information.
"Never a moment's rest, its always, 'seize her' or 'grab him', or 'go terrorize that old lady'. I'm one pooped spook."
- —Bakemon, moments before being ambushed by Tai and Agumon... it's easy to see why he hates the job.
Gennai: "The fog barrier surrounding the entire district is not a natural phenomenon. It's Myotismon's doing."
Izzy: "Well, duh!"
- —Izzy's less-than-subtle way of pointing out Gennai stating the obvious.
Kari: "Do you think maybe my daddy got away? He's all right, doncha think? And Mommy will be too 'cause Tai's gonna rescue her, right?"
Matt: "Uh, sure he will, Kari. But let's remember, Tai's just one kid and he's fighting hundreds."
Kari: "Waah!! I want Mommy to come back!"
- —Matt, Mr. Sensitivity he is not!
"I knew this was too easy."
- —Patamon is hardly surprised to see MegaSeadramon.
"Tai is gonna be so mad at me!"
- —Matt instantly blames himself for Kari's capture, though in a somewhat casual way.
- When Sora tells Tai where everyone is, her belt is the same color as her pants.
- When Joe, T.K. and Patamon notice MegaSeadramon, Joe's watch is misdrawn.
- When Ikkakumon gets hit by MegaSeadramon's Lightning Javelin attack, Joe's right wristband is colored green instead of yellow.
- When Birdramon rises to fight Snimon, her lower jaw is the same orange color as her body.
- When Sora falls is knocked back by Phantomon, seperate frames show her gloves colored the same color as her skin, her belt the same color as her pants, and the sole of her shoe being white instead of dark gray.
- When Matt is being strangled by Phantomon's chain, the pink stripe on Tuskmon's nose is the same green color as his body.
- In the scene where Tai and Agumon run into the building, the black band on Tai's left arm is missing.
- In the original version, Tai's arrival at the convention center is the ending for this episode, where as in the English version it is moved to the middle of the episode shortly after his encounter with Sora, making Kari's capture the cliff-hanger ending for this episode.
- In the Latin American dub, MegaSeadramon is wrongly referred to as MetalSeadramon.
- Zudomon announces the episode title in the Japanese episode.
- This is the only episode where DemiDevimon uses his Evil Whisper attack.
