Hmm, that really sounds unfortunate... I assumed you'd be able to deal with either Benny or Chickadee before Dolly but I guess that's not the case, damn. Maybe try to stare at one of them a lot to delay their next move as much as possible, then deal with Dolly, then with the undelayed one and then the delayed one? It's a long shot, I don't know how the delaying works overall, but if it lasts for longer than just the time you're staring at them, it could maybe work?
