As he guided the missile to the portal Tony distantly heard JARVIS ask, "Shall I try Miss Potts?"

"Might as well." He replied, at least one of the last things he will see and hear would be his beloved Pepper.

Her picture flashed to the right of his helmet with the words 'call connecting…' As he got closer and closer he began to worry whether she would pick up or not. He needn't worry.

She picked up, a warbled; "Tony." crossed her lips. A deep sense of peace filled his core at the sound of her voice.

He let out a reverent sigh of her name before he passed through the portal and the call was disconnected.

He released the rocket, letting it fly on its destined path toward the Chitauri, the spaceship exploded as is suit lost power. The picture of Pepper slowly faded from view, and as Tony slowly closed his eyes, her face and voice superimposed in his brain, he gave a sigh of contentment and slowly faded. Falling into the deep sleep.
