When its just mooks, like the Lec-sec or the Exo-suits, then I'm giving y'all full autonomy to do with them what you wish (within reason).

If it's named villains then that's when I'm getting involved, unless otherwise instructed.  

In this situation I would say that Twilight's attack worked and slowed the guards down, giving Madcap the time she needed to retrieve her punchline.
