"Thanks. I'll pay you back when I get a chance. And yeah, I'm sure it'll be fine." Zack flashed her another smile and took the card. He disappeared into the back, glad that the gym's layout wasn't all that different from the gyms Shinra kept for their employees.
Once he found the showers, he checked to make sure no one else was around to remark on the blood or the glow of the Cure spell. Then, he stripped down and did his best to dig out the bullets. He'd left his Buster Sword outside, safely concealed, but he didn't want to leave it there for long. After he'd scrubbed himself clean, he grabbed the materia and was pleased to see that the spell took care of the worst. He turned off the water and toweled off, then pulled some bandages from his meager supplies.
Zack headed back out to the front once he was taped up and dressed. "All set," he said, knowing that he looked significantly better, even if he was still a little stiff.
