>>55889334I got a couple scenarios for this
>Cerulean GymRuka jumps at the chance to gym-sit whilre Misty is out of town. Why? Because Cerulean Gym is basically a big private pool. So she puts on her cutest Bikini and a beach towel and a pool chair and spends the whole day lounging, swimming and playing. Or rather she would but every 10 seconds she's interupted by a trainer challenging the gym. And she wouldn't mind so much but a lot of them are just really bad. It's not even fun to beat them. By the end of the week she's bitter and annoyed and is basically one-shotting trainers for every battle. She isnt even getting compliments on her bikini!
>Saffron CitySabrina needs to go out of town and specifically requests for Ruka to take over the gym. Ruka initially wants to refuse because she doesn't like Sabrina but Sabrina reminds her that as a Champion its her job to help out gym leaders. So Ruka begrudgingly takes the job. The good news is that she can finally work alongside Jynx. Ruka wants to make the battle easier for trainers since she had such a hard time so she only uses Jynx. Even so she ends up winning every battle amd trainers complain she's way tougher than Sabrina. When Sabrina comes back she looks smug and explains that Ruka has gotten to be such a strong trainer that she's as much of an insurmountable challenge to these trainers as Sabrina was for her. Ruka gets all pouty and claims she's not like Sabrina and that all the trainers that challenged her just aren't very good. Sabrina chuckles to herself at Ruka's bratty hypocricy.
