Tony knew she was struggling to help him to his room. He was feeling dizzy and weak and tried to help her by trying to walk. He leaned on her a bit. He didn't know what was wrong with himself.
He was closing his eyes a bit. He shivered a bit.

Once laying down Tony groaned and closed his eyes. His head was hurting him. "What is happening... Pepper? I'm so confused." He whispered. He had a feeling she wouldn't leave him alone now.
Bruce was on his way to Stark Towers.
Tony wanted to be feeling himself again.
