(Seeing as Nurse Joy's a general character, you can control her when you post you response, Selena)
As much as Sethos agreed that he should probably get to the Center as fast as possible, he wasn't about to leave his new friend behind. Sure it wasn't like she would be hobbling for a mile to catch up, but it was the principal of the matter. He had a feeling that her injuries were getting worse, too, so he wasn't about to part until they were to be treated. Even when they were at the doors, he didn't take the invitation to go ahead. "Nice try, but we're going in together," Sethos said, stepping on the pad to open the automatic doors before directing Rebecca with him into the Pokemon Center.
The inside of the Center was just as awe-inspiring as seeing just how large it was from the outside. There were numerous waiting benches and chairs in the lobby before the Nurse's desk. Neither Nurse Joy nor Chansey were behind the desk, but the PR chimed a melody signaling that Pokemon in their care were all healthy. As Sethos and Rebecca traveled down the isle of seats, Nurse Joy and Chansey were coming out of the operating room with six pokeballs on a moving trolley. A trainer got up and hurried to them with a content smile on her face. "Alright, your Pokemon are in tip-top shape and ready for your gym battle later today," Nurse Joy said as the female trainer took her Pokemon and placed them in her bag. The trainer gave thanks and rushed down the isle, bypassing the two on her way out. Gym battle!! I forgot I'll have to fight in Pewter City again! Sethos thought, not noticing that Nurse Joy was approaching them, Ugh, it wasn't easy the first time, and I doubt it'll be different next time--
"Hey, haven't I met you before?" Nurse Joy asked, now a few feet in front of them. Sethos managed to brake out of his rant before he looked distracted.
"Er, yeah. I'm the boy who delivered that herbal medicine a few months back," Sethos stated, avoiding the obvious truth that he visited a couple weeks ago with Squirtle, "Will you be needing another shipment soon? I can place an order with my grandparents right away."
"That's right! Sethos, right? Thanks for your help!" Nurse Joy said, then looked over at Rebecca, "Oh, is she your friend? I guess you're here for her leg, huh?"
"We're both roughed up, Nurse Joy," Sethos added, "Rhyhorn got a little startled, and we both took a fall. Rebecca has a twisted ankle, and I got a concussion. Our Pokemon need some treatment, too."
"But if you two fell because Rhyhorn got startled, and it happened as I'm guessing it did, both of you should have sore backs from the fall," the nurse said, Sethos reacting with a surprised "eh?" sound, "You two did fall, right?"
"Y-yes, but neither of us got sore... We must be lucky, r-right?" Sethos asked hesitantly, trying to play off the question, "Will you help us?"
"We'll do everything we can. Chansey, take Sethos and get him sorted out. I'll take Rebecca into my care," the nurse said, Chansey walking over to Seth and tugging on his arm to follow her. Sethos waited until Nurse Joy secured Rebecca, and then slipped away. Rhyhorn grunted a temporary good-bye as he followed behind his partner.
"I'll be fine! See you in a bit, Rebecca!" Sethos promised, calling out as Chansey led him away.
