Charlie heard his words but didn't want to leave him alone, especially being clearly outnumbered. She hesitated for a moment before sneaking away, quickly heading downstairs to tell the others. She just hoped by the time she told them it wouldn't be too late. Tears started to sting her eyes at the thought of the brothers losing another family member, especially after the fight he had with Leo. 

She pushed the thoughts away as she spotted the others, running over towards them before quickly recoiling as she saw something fly quickly through the air. She was too late to warn them; the Foot were already here. She watched in shock as Raph crashed through the sunroof, glass and wood surrounding him. He wasn't moving. "Raph!" She exclaimed, running over with April and Donnie. Tears stung her eyes once again as she silently begged him to still be alive. 

"He's alive. Barely." Donnie assured them before looking at the few ninjas that had jumped in after their brother. Relief washed over Charlie before anger took over. These ninjas had the nerve to attack April, cause Splinter's disappearance, and now hurt her friend and threaten his brothers. She stood up, getting into a defensive stance.
