Amour - Ending Explained

The Climax: After telling Anne a calming story about his childhood, Georges suddenly pins her down and smothers her with a pillow until she dies. This shock violence is the culmination of his promise to end her suffering.
The Aftermath: Georges tapes the bedroom door shut, sealing her body inside. He begins to hallucinate noises and eventually sees Anne washing dishes in the kitchen. She is healthy and calm. She tells him to put on his shoes, and they walk out of the apartment together—implying Georges has died (suicide or natural causes) or completely detached from reality.
The Final Shot: The daughter, Eva, enters the now-empty apartment. She sits in the living room, surrounded by the silence, realizing her parents are gone. The film ends with her alone in the space, emphasizing the void they left behind.

The Ending: The final scene where Georges leaves the apartment with a 'healthy' Anne is widely interpreted as Georges' death. Some view it as a hallucination before he commits suicide (perhaps by jumping out the window, or starvation). Others see it as a spiritual representation of their souls reuniting.

The Pigeon: While Haneke claims it is 'just a pigeon,' critics have interpreted it as Anne's soul returning to say goodbye, or as a symbol of the 'Holy Spirit' offering peace. The fact that Georges captures it (death) but then releases it (letting go) suggests he has found peace with his action.
