Clary 5 months

"CLARY ! Get your skinny ass back in here!" Clary sluggishly ran back into the infamy past Jace, Alec and Maryse, still patiently waiting. Iz looked passed out on the bed. Her usually styled reaves black hair stuck to her still sweaty forehead, the sheets crumpled around her having rips in some places where she clawed at them. Simon sat in a chair beside Iz's bed looking petrified at the small wailing child in his arms.

A little breathless laugh left Clary making Simon snap his head up. His eyes looking very panicky. "Clary, please please please help me. Make him stop."

Clary laughed again and made her way to the duo. "Little man why you crying so much." She said gingery picking Simon and Iz's newborn son out of his fathers hands. She turned to Iz and placed the baby on her chest."See now he's quit happy and feeding."
