The 'fight' scene is a main path event. Both the boutique and cafe events lead into this scene.
If you're on the boutique path, you will encounter Teri and Samantha briefly. This is to ensure Max has met Teri going forward, thus allowing the removal of an opening branch of future Teri events where she hasn't met Max.
There will be similar events for other characters as the game progresses for the same reasons.
Max has a simple choice in the scene, to what degree he intervenes.
Following the fight, Meghan arrives with her trainee, Ashley.
Ashley is a side character, like Genna, Fiora, and Tisha from the sports team (Monday Park event).
Side characters do not have Affinity or Persona stats or appear in the Relationship app on the Smartphone/Computer. They are not love interests in general but will have lewd scenes on the path of the main character they support.
Beta builds are for testing; please remember they may be unstable and unfinished.
You should start a beta build with a live save file, but never take a beta save back to the live version.
