The Bodyguards

If Lust Doll confronted Don without securing Arlene's help, they would face Don's guards first. This is tough battle, losing which leads to a Bad End.

If guards are defeated, Lust Doll would face the choice: spare Don, or kill him. Both choices leads to a Bad End; only difference is wether Lust Doll would be pursued by only police or police and Don.
