dead refuse to die quest

[ScarlettRose]

ok, can i ask why is the searstrike sisters apart of this quest, when the items you receive for completing it, only drops from the first 3 bosses, and not the searstrike sisters? i mean, it doesn't make any sense at all to me. one, they're not even dead and two, the drops they do drop, are not even close to what you get from the other three.
