A/N: Let's say you lost an important battle, or something happened that made you sad. What would she do to help with that?
Marnie: It's rare for you to show your emotions like that, so she wouldn't know what to do at first. If you want to talk about it, she'll listen, but if you won't, she'll respect it. Although she is willing to do what she wouldn't do with anyone else, cuddle.
May: She would offer a big hug and often saying sweet things to you like compliments and such. Sometimes she would take you to the far reaches of the region to get some fresh air and chill together for a while
Gloria: She would pick the best spot for camping and take you there, but also pamper you by cooking your favorite dish (the one she's been practicing so much) maybe you'd make a small fire and sing together
Serena: Serena knows the most beautiful places in the region, so she would book a few days in a nice hotel in one of those spots, walking out with you around the city at night and reminding you how wonderful you are to her
Courtney: She would take action on the cause of your despair and make them pay for bringing you down like that...and maybe watches movies with you after that, your pick!
Sabrina: Similarly, she would go deal with the source of your sadness and if it's someone who wronged you, she would scare them into apologizing. But that's not all, she would close the gym for the day and spend the rest of it cuddling with you or joining you in whatever activity you'd like
Cynthia: You two would talk it over some ice cream, maybe even taking you to some archeological wonder but regardless, she would always offer the comfort you need, be it with her words or her actions
Nessa: As soon as she knows that you are sad, she would cancel her appointments for the day start to plan something for you. Whether it was taking you for a swim in one of those breathtaking places only she knows of or going for a snack at your favorite restaurant, Nessa would always make sure that you feel at ease
Bea: She would let you take it out on her in an intense sparring match, it doesn't need to have Pokemon involved. Making you concentrate like that and focusing your emotions on that match would often result in a satisfying match. After that, she would meditate with you, holding your hand to remind you that no matter what, she would always be there for you
