In comics canon, Matt can resist Killgrave's powers.

Let's see this play out in the TV universe (ideally with a better justification than "willpower"). Any era/age--maybe Stick trains him to resist psychic assault b/c he knows PM's out there. Maybe Killgrave is involved in Elektra's dad's business. Or maybe it's closer to the present, and he decides to go after another hero before targeting Jessica a second time. Either way, I want to see Matt trying to push back like the stubborn bastard he is.
