Tony Stark the Invincible Iron Man hovers over a large mechanical device that beeps and whines.

"Alright start test number 8-7." Tony tells B.O.S.S. as he pulls away. The machine flashes a bright light, above Stark Satelites redirect outward to space and send out a long low level gamma beacon.

"Come on this has to work." Stark says as he taps away at holographic keyboards.

The machine starts to whine. "Crap!" shouted Stark, "B.O.S.S. activate outershields!" Blue light wraps around device just in time as it explodes in a brilliance of orange light.

Tony shields his eyes and when he looks again theres a black smoke where his machine was. "Mr. Stark ninety percent of the Satelites you have chosen for this experiment are no longer online." Came the A.I. voice of B.O.S.S.

"I'm sorry Tony but my field of expertise is Biochemistry." states Jemma Simmons as she removes her goggles from her eyes.

"No you're a great sounding board." Tony wiped the sweat from his brow.

"We really need to try to find those infinity gems. They're the only way to bring everyone back."

"Tony, I think its time we face the facts... You're infinity gems detector is ineffectual: your satelites search would be limited taking forever to scan the universe, and also now that the infinity gems aren't being used they may not be giving off enough gamma radiation to detect." Simmons said.

Stark clenched his fist. It was true, but god damn it with Eddie dead, and the wizard and kid dusted, he needed to find a way or why else would the wizard help save his life?

"What other options are there?" growled Stark.

"We might have one." said Steve Rogers walking into their lab followed by Natasha and Scott.

"Scott." Stark said shocked.

"Its a long story." Nat said.

"Damn, I was just about to say that." Scott said, "but it did sound cool coming from you so I guess...yeah."

After Scott excitedly explained his idea of time traveling through the quantum realms, Tony turned to Jemma.

"Well Doctor, what do you think."

"We agents of shield time travelled before but it was to the future going back in time is a completely different beast altogether. But you know all that with Natalie Kent." Jemma said.

"Yeah, and."

"Wait has everyone time travelled or dealt with a time traveler before!" shouts Scott looking at everyone in amazement. The group looked at each other before shrugging.

"Yeah but it was an Obelisk, which aren't available anymore." Jemma explained.

"Kang and Natalie had thirty first century tech." Said Steve.

"But my time travel plan is unbelievable."

"Using the quantum realm, yeah, we'd be dealing with Quantum fluctuation that kinda messes with the Planck Scale, which then triggers the Deutsch Proposition, understand?" Tony explained.

Nat, Scott and Steve look at each other with confused looks as Tony grabs for a water bottle and chugs it.

"It means it be impossible to come home again." Simplified Jemma.

"Thank you, Doctor." Tony said with a smile. The two had gotten pretty close over the past few months since starting on this project.

"But I did and...so did Janet."

"Janet might have been on the surface of the realm, while you were lucky to come back when you did." Stark said.

"Tony," Jemma interrupted. "Our project isn't working maybe, maybe this can."

"Please, we have to try." urged Nat. Tony looked at his friends before sighing.

"Give me a couple of days to try to figure out how to tackle this problem." Tony said.

For the nextt twelve hours, Tony and jemma build HOLO MODELS: Penrose diagrams, wormholes. Tony studies a star-shaped capacitor, when he looks over Jemma is asleep at her desk for her its been 32 hours without sleep.

Keeping his voice low he asks, "B.O.S.S. can you do me one last favor for we pack it in for the night"

"Of course sir." said B.O.S.S.

"Alright run a sim this time, in the shape of a Mobius Strip, inverted." Tony said taking back as blue hologram appeared before him. The capacitor glows as a holo-man drifts into a circular wormhole, looping before returning to the place it first left.

"Model Success." Said B.O.S.S.

"Holy shit!" Stark said stunned. He rushed out of the lab ran into the dorm section of the Avengers Compound. He pounds of Steve's door.

"I'm up." Came Steve's tired voice. He opens his door surprised by the excitement on Stark's face.

"I did it." Stark said, "We need to get everyone."
