Jirou had come running from the Pokemon Center after healing his team. His guys wouldn't have been able to take the leader on in their current state, and his thoughts were turning to learning about her Pokemon [thus security] by faking a gym battle. When he'd beaten the gym trainers in his way he'd fumbled with the keys, in the end settling for putting them on his keyright. Except now he'd remembered he'd have to take them off afterwards - if they remembered to tell him.
He went back through the gymn to the outside arena, where he spotted Lulu sitting on the grass and went over to see what she was doing.
Bending over, he took a deep breath. "Man, that was close."
