Pepper didn't respond with any kind of verbal indication that she had been there since the night of the shooting, but it was obvious on her facial features and her puffy eyes. She wasn't about to abandon the man who saved her life.
"They..um.." Pepper didn't exactly know how to tell Tony what they did. She might as well just say it, right? "You were going to die. There was shrapnel. I told them to put the arc reactor in." She was hoping Tony wasn't mad at her for that. "It saved your life. I'm so sorry I didn't believe you, Tony."
