This is how rebuilding the Gateway goes in Crash's, Thomas' and Ryan's Adventures of LEGO Dimensions.
[Batman, Gandalf, Wyldstyle, Ryan, Crash, Thomas and the gang arrive in the Gateway room]
Ryan F-Freeman: Uh oh. Everyone. It's gonna blow!
Buck the Wiesel: Take cover!
[They do and the gateway explodes then bits go everywhere and the Keystones get sucked into the vortex]
Rigby (EG): You got nice eyes, Ivy.
Bertram T. Monkey: Get off... [grabs Alvin] My face!
Wyldstyle: Well, I don't know what you did, but, we're still alive.
Gandalf: Are you sure?
Princess Ivy: Yes, Gandalf.
Ryan F-Freeman: Ivy.. You're sitting on my back.
Princess Ivy: Sorry, Ryan.
Crash Bandicoot: This technology looks advanced, Batman.
Batman: Yes, Crash. That gateway created the rift that brought us here.
Gandalf: Which gateway?
Princess Ivy: The one that got blown up?
Gandalf: Hmmm. Then perhaps...
Sci-Ryan We should rebuild it!
Wyldstyle: Good thinking, Sci-Ryan.
[The Cyberlings vocalizes while Ryan, Sci-Ryan and Wyldstyle gather all of the bits]
Ryan F-Freeman: Let me do this.
[Ryan builds the Gateway like a Master Builder]
Sci-Ryan: Cool. Now we need something to power this up.
Batman: Good idea, Sci-Ryan. Good thing I can build a mini version of my Batmobile.
[Then he builds a mini version of the Batmobile, and then powers up the gateway]
Batman: There. That'll power up the gateway.
[Then the gateway started working again]
Gateway Keeper: Re-routing from back-up power. All systems are go. Limited system functionality restored.
Wyldstyle: Limited system functionality? Am I going to lose an arm if I go through that thing?
Thomas: It looks unstable. At least this won't kill me or turn Crash into a pink panther if I do this.
Crash Bandicoot: What?! Pink panther?! I'm an orange bandicoot. Anyway. Batman and I saw some glowing parts get sucked into the portal. Must have been important somehow.
Aria Blaze: Well. It seems to be alive, Crash.
Ryan F-Freeman: I can sense something through that portal, Aria. Why you feel like you are with me?
Aria Blaze: I think I like you with me and my sisters. Yeah. Cause this is our adventure together, we can get some new allies when some of our friends get turned into stone.
Matau T. Monkey: Could this portal lead us to the missing oval bits?
Batman: Could be.
Wyldstyle: Or Metalbeard.
Batman: Couldn't be.
Evil Ryan: Guys. What Gandalf said. Remember?
Metalbeard: [off-screen] AAARRRR!!!
Ryan F-Freeman: What's that?!
Adagio Dazzle: Is it another siren or Metalbeard?
Twilight Sparkle: Ryan?
Ryan F-Freeman: I think it's Metalbeard, Twilight. It sounds like he's in trouble! Or he's happy. He uses his catchphrase "Argh!" for a lot of things but either way, we'll have to find him.
