In front of the whole team someone (Perhaps Fisk) Menaces Matt in a sexually coercive or rapey way. Maybe Fisk is in a position of power and wants to toy with them. But he doesn't get a chance because Jessica flashbacks to Killgrave and goes bezerk. Killing the bad guy and seriously freaking out the team. Matt is disturbed but very moved that she cares.
