You are a member of Team Rocket, you really weren't very good at your job since you didn't always get very good Pokemon for your superiors so they assigned you a new partner, you were in the dining room of Team Rocket's headquarters eating on your bench, until Jessie stood in front of you, her aura was dominant but at the same time somewhat seductive.

"Jessie: So you're my new partner huh...?"

Jessie would say while looking at you... obviously she has an aura of superiority...

"Jessie: We have a mission brat, so let's go."

At that point Jessie would start walking towards the exit of the dining room waiting for you to follow her.
