You make an acting under fire roll directly afterwards. So for the Healing touch move, they roll ... +wierd to heal someome, then get the 7-9. The patient is healed, but the patient's brain assaults them with psychic awfulness! They roll +cool (or whatever, depening on their moves, some playbook moves switch acting under fire to a different stat), and if they miss or do a weak hit, then the MC can make some kind of move, as the circumstances depend.
Same thing with manipulate. Manipulator rolls their Hot (or whatever, again some moves change this) against the Manipulatee, and picks "the stick", rather than "the carrot" (or both, if they get an awesome roll). If the person manipulated (always a PC for this particular version of the move, NPCs get a different set of rules) says "no thanks", then they must make an acting under fire roll. They still get to say no, but then have to make an act under fire roll because the manipulate has really thrown them, and they need to keep their calm. If they miss the act under fire roll, the player does NOT suddenly change their mind (they've already said no) but it does mean that the MC gets to make a hard move against that person, capitalizing on the PC's momentary lapse of attention to have terrible, terrible things happen.
For extra super fun, the manipulator could also hinder that person's act under fire roll, to really amp up the awfulness.
