(That is a pretty good plan, actually.)
You order on of the two remaining followers to shoot him in the leg, which makes him finally drop the sword. You step to absorb him, but then stop. It would be a rather useless form to have as it is right now, but if you just had the knowlege of what he looked like and not the body, it would be far more useful. You holster the pistol, revert to True Form, and focus on him with your hand stretched out to him, and see him eventually flop down, passed out from the combined pain of being pinned to the wall and the mental effect of assimilation. You then have a follower call for an ambulance (but using Officer Quartic's name) while you remove the dagger, throw it out into the street, and with the other follower's help then attempt to keep the dagger wound from bleeding too much more, since as stupid as he was, he is still important to your plans. At least for some moments longer, anyway. You then return to Officer Quartic's body, though the effort used to pin him there will leave her arms oddly muscular for at least an hour or so.
