Pepper sighed, "I don't know how long he's been ill. He still drinks to the point of getting bad hangovers in the morning... He's been getting five hours of rest a night and he's been snappy. He hasn't been himself really," she explained softly as she followed behind him. She knew he was good at hiding things it was why Pepper hadn't noticed anything until now. 

"Tony, he's here to help... You're not feeling good," She explained only to gasp when she saw his fist connect with Bruce's face. "Tony?!" she shouted as she rushed over to Bruce. "Are you okay Mr. Banner? What's gotten into you Tony?" she asked sounding furious with him.
