Bruce was looking at her "MMmm well I am not sure if you are going to have to convince Tony to access his project plans." He knew that Tony couldn't be stubborn for ever. "Tony your life may be at risk , can you please not hide your project anymore."
He could see Pepper was freaking out. 
Tony was curled up and mumbled "Too dizzy and tired." He really didn't want to do anything. He knew it could be dangerous to let anybody else know. He didnt want Pepper hurt.

"Tony," Bruce looked at him seriously "This could be important." He sees Tony is staring at him and seeming paniced. Tony backed up and was coughing badly. Bruce gives Tony some injection to help calm Tony down.
"I'll do my best Pepper." Bruce replied.

Tony was looking pale and dizzy. "Fine..," he grabbed his laptop and accessed his data and plans. He was coughing badly. "Its a new invention.. Telling you may be dangerous for your safety."
He was breathing deeply "The project has a new element..." He was still unaware how dangerous the element was to his health. He gasped painfully. He had no idea what it was doing to him. He screamed in pain.
