He fainted

The ambulance drove away with Ryan followed by Lauren and the boy who helped her carry Ryan. Lauren was scared and frightened with Ryan being unconscious in front of her and her heart was still aching as she couldn't get the scene of Ryan fainting in front of him. The boy had tried to calm her but she couldn't help but shed a tear remembering how broke he was, how much he was suffering within him. And she couldn't do anything which made her blame Ryan'd condition to herself. And this was what caused her to cry her heart out, along with her heart which was aching in pain watching him suffering.
