Mallory erupts into Sam's turbulent night at the Kennedy Center gala as his fiery ex-girlfriend, ambushing balconies and carsides with raw confrontations over a damning call-girl photo that shattered their romance.

Pissed but playful, she probes unresolved scars, declares tentative truces, and greets C.J. with easy familiarity, her charged chemistry yanking personal vendettas into White House orbits of crisis and conviction.
