Here's another heat sink, not connected to the first. Waste heat can go there.
And soon enough Glam appears. "'Sup?"
"Behemoth is heading for this nuclear plant and we're slowing it down but not stopping it. What are the odds it can make a humongous explosion if it gets here? So I'm going to move the whole building far away. Problem is, if I move the building the coolant pumps can't get water from the river anymore and explosion happens anyway. So I need a freeze ray."
"I can store heat and dump it elsewhere, with some loss."
"Which in this case is a big pro," they agree. "Okay, super freeze ray, can I set something up to scan what you're doing and serve as inspiration?"
The other cape shrugs, but apparently his job takes some concentration so he doesn't say anything more.
"From what I can hear on comms we have about half an hour. Can I help somehow?" Other than believing as hard as she can that Glam can do whatever they want, that is.
"Okay, now you can, I'll need you to help me assemble this, real quick."
And pieces start appearing and Mountain's help is requested.
She helpfully assembles things, being a bit showy about it. The Nuclear People still watching don't know what to expect a freeze ray to look like except 'big and tinkery' after all.
Buuuuullllllshit.
There's enough spooked physicists and hopeful capes around that it does in fact work quite well, however.
She flies outside, perches on the lip of one of the cooling towers, and lifts the entire facility - reactors, cooling towers, radioactive waste and all, out of the ground. She proceeds due north at significantly-greater-than-highway speed - certainly faster than Behemoth is managing with plenty of capes still working to slow it down.
After twenty minutes, she lands the facility a couple hundred miles north, far away from any significant towns and near another river, changing the earth around it to match. The coolant pumps come back on without a hitch, and the squad of physicists tell Glam and Transfer that they can take a break.
Is the fight still going on? Because if so, Mountain is going to throw herself right back into it. She takes Transfer with if he wants a ride.
Glam comes with, and would like to know that as well. Apparently the fight is still going on, but the lack of a target has changed its character somewhat. Enough that by the time they arrive, Scion's there.
Mountain protects the rest of the city from the shockwaves and fallout of the Scion-and-Behemoth brawl as best she can. Which is only about halfway.
"Well, that could've gone a lot worse than it did."
Mountain is still doing medevac, but can spare a moment or two to chat. "Yeah. I think they just keep getting tougher closer to the middle, like twice as tough every foot. Your lightsaber shaved off a whole leg's worth of skin but wouldn't cut deeper."
Glam themself is creating floating litters to carry the injured. "Yeah. I need to talk to you later, by the way."
Medevac proceeds. Mountain is asked to put the nuclear plant back where it was before and remove your heat sinks and so on now that Behemoth's gone, thank you very much. They might even be able to start it back up in a month or four. The planes to take capes back home come and go and eventually Glam and Mountain are in New York again.
And Glam draws Mountain aside, which by cape standards is "floating around somewhere," and asks, "Is there something you think I'd be interested if you told me?"
"I know how your power works. I had a guess the first time we fought and knew for sure after that time we sparred. I hadn't planned to do anything with this knowledge, but against Behemoth you want every advantage you can get."
"In my homeworld there are several types of Fair Folk who can do - illusions that work until you realize it's a trick. Working with expectation. I had to fight some, once, and your power struck me as a very similar kind of thing. I know perfectly well that you'd be ruined forever if anyone but me figured it out, so I have no plans to tell anyone unless you go hard villain."
"I'm not out to get you. Perhaps I should have told you I figured it out. I didn't- I'm not good with people. Social things."
"...Well, I know how to keep trade secrets, at least. You have to if you want to stay ahead as an enchanter."
