Why Did Lilly Kill A.B. Wynter in The Residence?

What Were Lilly’s Motives for Murder?
Lilly Schumacher (Molly Griggs), the White House Social Secretary, was tasked with overseeing social events and revamping traditions. However, her efforts clashed with A.B. Wynter (Giancarlo Esposito), the Chief Usher, who upheld long-standing White House customs and prioritized staff welfare.
Lilly despised the institution, treating staff members as disposable employees rather than a family unit. Her ambitious plans included corrupt financial dealings, pushing expensive contracts to questionable contractors to siphon funds. Wynter uncovered her fraud, meticulously documenting the illegal transactions in his journal and confronting her during a closed-door meeting at the State Dinner.
Faced with exposure and ruin, Lilly acted swiftly—poisoning A.B.’s drink, attempting a blunt-force attack with a vase, and ultimately bludgeoning him to death with an antique clock. She then hid the clock in a sealed-off passageway, orchestrating a crime designed to deceive investigators.
