"Welcome to my gym, are you here to test out strength. Or are you here to get your ass handed to y- oh. I kinda' recognize you. I believe Lynn said she has a friend that fits your description."
While in Jubilife, Blue had heard of the training facility ( gym?? ) established there. Curious as to their training methods, she decides to check it out. To her surprise, the man that greets her seems vaguely familiar for some reason—
Lynn. Oh, yeah. She remembers now. This guy is squarely in the HEY THAT'S ILLEGAL— zone, whatever that means. She'd offer her condolences though she has no idea what kind of guy he is yet so she'll withhold them for now.
"Nice to see Lynn's been talking about me, I guess." Hopefully only good things, but who knows... The day she kicked Lynn's door down and dragged her to breakfast apparently left a deep impression on her friend. "I'm Blue. A pleasure to officially meet you. I take it you're the leader of this training facility?"
