Ladies and gentlemen, awesome has entered the dimension.
"Ok.  So if my math is right---and it always is---Stevie's stuck in dimension heeeeeyah."

Marie Claire pointed to the blue splotch of color on the wall-size display.  It was full of colorful splotches, each one representing universes as layered on and around each other.  Dimensions, really, but they didn't look very "dimensional" all colorful like that. Instead they looked a bit like a crazy Rorschach test.  She waited for the rest of the Avengers to take in the destination before changing images, a zoom in of a lighter blue thread that seemed attached to the splotch.

"We're the green dimension.  See the blue line?  That, my friends, is a type of wormhole. It operates on a specific vibrational frequency.  Using the last of the data from Stevie's suit and some of the data we have from the unfortunate Zero Point Gravity Incident."  She paused for a moment, a grim face of sadness washing over her as she thought of the loss of a friend and two entire neighborhoods in the city that LITERALLY disappeared into a mess of non-matter that one might call a singularity (suck it, CERN.)  "Using that data I've created a device that will let me hop over there, get Stevie and hop back."

As predicted Mike didn't like this.  He started to object but there was no objecting to Marie Claire Pym whens he was either shoe shopping or had an Idea.   After a sharp look from her, he shushed.  Everyone shushed.

"Alrighty.  Then tomorrow I go get Stevie.  Someone hide the car.  I want to mess with her good."

There was a little burst of light and energy and Marie Claire Pym popped into existence right outside the Avenger's mansion.

And promptly smashed into a tree that wasn't there in her own world.

"Oh goddamnit I broke a nail. "
