YMMV / One step backwards and Three forwards

• Moral Event Horizon: Betraying Ladybug was bad enough, but Alya crosses the line when she responds to her parents' efforts to keep her safe by running away from home and joining Giulietti's criminal empire, working to help him unmask Paris' superheroes and eliminate them.
  • Alternately, it's revealed through Kagami's musings in Act 2 that Alya helped set up Luka to die by requesting that Ryuuko patrol with her rather than with Viperion. That could easily mark the moment where she crossed the point of no return as well.
