The emergency teleportation, combined with an adrenaline rush and the (quickly fading) power of the Grid, served to disorient Leon rather badly. He felt light-headed and sick as he appeared in the Academy, and he almost immediately fell to his knees.
But there wasn't time to be nauseous because his friends needed help. He shook his head and tried to clear it before he looked around at everyone.
Lindsey was obviously injured, and Leon didn't need Desmond telling him that the Yellow needed medical attention. "C'mon, man, on your feet, time to go," he said as he bent down to help his friend up. He glanced around to see if anyone else was in obvious need and spied Nic slumped over. "Fuck," he muttered as he reached over with his foot to tap one of the Alphas. When it turned to him he asked it to fetch some stretchers and medical staff, and it went scurrying off.
