Sorcha means bright and intelligent. Sore-sha

I worked out that Tony Stark is meant to be in his late 30s (born 1976). So in this fanfiction he is 36.

There is a large age gap between Sorcha and Tony- 12 years. Sorcha is 24 and born in 1988.

Tony was rapidly flying towards Stark tower. Two minutes away. The damage to his suit was preventing him from going full speed but he was still rocketing forwards.

Everyone watching was silent. Thor, Clint, Natasha, Steve, even SHEILD and Hulk were silent. Tony kept leading the missile.

Far away, a light started flashing on a SHEILD monitor. The worker ignored it- too busy watching him fly towards his tower.

Time was moving agonisingly slowly. Each second felt like 10 minutes.

The comms units crackled to life.

"I guess we would have a made a pretty good team in the end" Tony sighed.

"Indeed friend Stark" Thor said solemnly.

"Rodger that" Steve added.

Tony was a minuet away from the portal.

He saw something moving rocket fast to his left but directed his focus on the missile.

Suddenly, a loud scream echoed through the comms units.

"NOOOOOO!" The women screamed.

Tony ripped his eyes away from the portal.

The 'special' suit was rocketing towards him.

"No!" Tony yelled, "Get away from here!"

She didn't listen. Instead, she flew alongside him. She held onto the missile next to him.

They were 30 seconds away from the portal.

Suddenly, she kicked him. The force of the suit sent him flying away from her and the missile.

Tony yelled, in grief, and anger as she flew into the portal.

"SORCHA!" He shouted, but she was gone.

One of his boot thrusters sparked and died. Quickly, he flew back to the ground.

A huge explosion made h looks desperately up. He could see a bright light in the portal but nothing was in the sky.

Tony sat on the ground, leaning against a car. He only dimly heard Steve give the order, "Close it".

He slumped backwards. A tear managed to escape his eye but he clamped his eyes shut before any more could follow. Someone was shaking him but Tony didn't care.

"She's gone" he moaned, "Gone"

Then he heard a relieved shout from Thor, "They made it!"

Tony looked up so fast he pulled a muscle.

There she was. Coming straight towards them. Then he frowned. Coming too fast.

"She's not stopping!" Steve cried in alarm.

Tony wrenched himself to his feet. He tried to take off but both his thrusters flickered and died.

Thor as swinging his hammer, but he wouldn't catch her in time.

With a roar, the Hulk launched himself at the falling suit. He caught her and they crashed into a car.

Tony ran to her side. Thor ripped off her face mask but Tony didn't care.

Sorcha didn't move. Tony felt for a pulse. Fresh tears pushed themselves out of his eyes. Tony didn't notice. No heart beat.

He gathered Sorcha's body in his arms. He rocked backwards and forwards, hugging her.

Emotional displays were completely out of character for Tony but here he was, sitting on the road, crying.

Suddenly, Hulk roared. Tony would have yelled at him but Sorcha's eyes flew open. She gasped. Tony hugged her tighter.

"Can't... Breath" she wheezed.

A furious Tony held her at arm's length.

"Don't you ever -EVER- do that again!" He yelled.

Tony stood up and helped Sorcha up. She was rather wobbly so she leant against him.

The other Avengers members were gaping at them- even the super spies.

"Who... Who... Thank you" Steve managed, staring between Sorcha and Tony.

"This is Sorcha" Tony explained, "My little sister"
