Looking out of the back window, you give a brief glance to Breeze, who's keeping up with you quite well. Skating on her little clouds, she's not gonna be impeded by traffic at all, plus couldn't she just fly? You decide that the chase isn't going to work.

– "Nerd, listen here, I've had enough fighting for now." A lie, but maybe it'll help sell your idea. "You're going to park the car, and then you're going to tell the $%#&! who's chasing us that I'm waiting for her on the rooftop for an epic duel! And then I'm going to bail and leave you alone. Got that?"
The nerd doesn't bother with answering and just slams on the brakes while swerving into the nearest alley. She then rolls out of the car and starts to limp away unsteadily. You lay low, powering the suit to the maximum.

Breeze catches up in seconds, rounding the corner and quickly getting between nerd and the presumed monster chasing her. With no obvious foe in sight, she checks on the civilian. The exhausted woman feeds your brilliant cover story to the HERO (she omits the slur though). You get ready to leave the car and walk away as soon as Breeze leaves, but she just calls someone on the radio.
– "Yeah, I got the hostage, the mold monster is supposed to be on the rooftop? Check if you can surround him. Yeah.. Yes, I'll stay here for now."
Damn it! She was supposed to leave! Well, no matter. She'll go away eventually. You'll wait.

A bunch of cars come, including an ambulance. They give nerd a blanket and cart her away. Feds come, realize they missed the nerd and question Breeze instead. Rest of the elementalists fly in on the ice platform. Ice King tersely exchanges info with the feds. Fire woman cheerfully offers to burn down the contaminated car you're hiding in, but everyone convinces her not to start a car fire in a random alley. Eventually everyone leaves except for a bunch of soldiers in hazmat suits who are too busy trying to hook the nerdmobile to the tow truck to see you slip away. That was a lot of close calls in rather quick succession, but you're clear now.
