Cut to outside the bus as it pulls past a parking lot. The screen then fades to display a large building in the city, just as the bus passes by. The words "PRAGUE, CZECH REPUBLIC" appear in white across the screen before fading as the camera pans up to show the city in a state of celebration, the sky now dark.]

[Cut to a quieter street where the bus pulls into a parking spot outside another large building]

[Cut to inside the building, where two men in suits pull open the doors for the class. The camera switches vantage points, showing the large, fancy reception area of the hotel, which even includes a grand piano and pianoman]

Isabella: Wow, this place is so classy.

Classmate: Yeah, so why are we here?

Thaddeus: [cocky] Speak for yourself. [chuckles] I'm home. [turns back to his phone where he's obviously gone back to vlogging]

Mr. Harrington: What can I say? The squeaky wheel gets the upgrade grease. Uh, everyone get settled in, rest up because tonight, big surprise, is Prague's annual...

[Phineas's phone buzzes]

Mr. Harrington: Carnival of lights!

[Mr. Harrington gestures excitedly to a poster advertising the festival. Phineas signal Ferb and they walks a little ways away to answer his phone]

Phineas: Hello?

Lyla: Boys, it's Lyla. There's an earpiece with your bags. Put in on and await further instructions. Understood?

Phineas: Uh, yes, ma'am.

Lyla: Yeah.

[Baljeet and Buford hurries over and throughout their conversation, they send quick glances back towards their class]

Baljeet: Hey, guys. Look, I am so sorry if I seem preoccupied with my relationship. You know, I still got your back.

Phineas: No, no, it's all good. Don't worry about it.

Baljeet: Okay. Great, great.

Phineas: It's fine.

Buford: So, what's the status on the whole Elemental thing? Where's it going to happen?

Phineas: Uh, here in the city

Baljeet: Phineas, we are here.

Phineas: I know, I know. It's not good. It's- We're figuring it out.

Buford: You two better do something. Cause We're all counting on you.

Ginger: [calling from back where the class has now clustered around Mr. Harrington as he shows them something] Baljeet.

Baljeet: Yeah. Yeah, coming.

[He hurries back over to the rest of the class. Buford follow him.]

Mr. Harrington: The good news is, we've all got our own rooms.

[As the class around Mr. Harrington exclaims in surprise and joy, Phineas stares off into the distance, thinking and worrying about the elemental]

Major Monogram: (O.S.) Phineas? Phineas!

[Phineas startles and turns around as we cut to a makeshift O.W.C.A. base.]

Phineas: Yes, sir?

Major Monogram: That thing's going to be here in a few hours. Are we boring you?

Khaka peu peu: He's not bored, he's just thinking about how you kidnapped them.

Major Monogram: They had obstacles. I removed them.

Carl: They still won't evacuate the city.

Major Monogram: (groans) Idiots. So what's the plan, Boys?

Phineas: We will be in the cathedral tower keeping watch for the fire monster. When that shows up, I will radio you guys, and then Khaka peu peu and us will-

Khaka peu peu: My name is Mysterio.

[He shoots Phineas a playful look. Phineas chuckles under his breath.]

Phineas: That's when Mysterio and us will move in.

Khaka peu peu: Phineas, listen to me. The best hope you have - the only hope - is to stop it here and now, no matter what the cost. Keep it away from civilians if you can, but, most important, keep it away from metal. If it gets too big, it'll be able to draw power from the Earth's core. After that, there's no way to stop it.

[Phineas briefly shares a glance with Monogram.]

Major Monogram: that's why I'll send Agent P with you to help keep the citizens safe.

Phineas: right the citizens which reminds me, our friends are here? And I can't help but think we're putting them in danger-

[Monogram stands up and walks over to Phineas.]

Major Monogram: You're worried about us hurting your friends? You? Who called a drone strike on your own school tour bus? We gave you a multi-billion dollar AR tactical intelligence system and the first thing you do with it? Is try and blow up your friends. It's clear to me that you were not ready for this!

[We cut to The boys, sitting alone on a rooftop. Mysterio flies up towards him with his helmet on]

Khaka peu peu: Look, Monogram asked me to come up here and see how you were doing. He just, he felt bad about snapping at you.

Phineas: (hopeful) Really?

Khaka peu peu: You guys know what sarcasm is, right? [He sits down, right next to Them] How you feelin'?

Phineas: I didn't think we were gonna have to save the world again. I know that makes me sound like such a jerk. I just... I had this plan with someone, and...now it's all ruined.

Khaka peu peu: (sympathetically) You're not a jerk for wanting a normal life, kid. It's a hard path. You see things, you do things... Make choices. People look up to you... Even if you win a battle sometimes, they die. I admit you were a worthy challenge when we first met. You're good kids. There's a part of me that wants me to tell you, just... turn around, run away from all this. And then, there's another part of me that knows what we're about to fight. What's at stake. And I'm glad you're here.

Phineas: Me, too. (worried tone) But...

Khaka peu peu: (friendly) You're worried about your friends.

Phineas: Yeah. I just feel like We're putting them in danger.

Khaka peu peu : Look, just... Get them inside and keep them in a safe place, for just a few hours. It'll be all right.

Phineas: It's really nice... to have somebody to talk to about this, you know?

Khaka peu peu : Anytime. And hey... (jokingly) We survive this, you'll have all summer to kill that Antonio guy.

[They chuckle. Phineas and Ferb grabs their backpack.]

Phineas: See you out there.

Khaka peu peu: Alright.

[They make their way down to the building and lands on the floor. An old couple takes notice and looks at him.]

Phineas: Scusi! Sorry, that's Italian...[He pulls the E.D.I.T.H. glasses out of his bag] Okay, uh, E.D.I.T.H.?

[The glasses initialize and Phineas waits impatiently.]

E.D.I.T.H.: Hello, Phineas.

Phineas: Hey! Uh... I need to find out a way to keep our friends inside for the next few hours.

E.D.I.T.H.: Let's see what we can do.
