The bank robber’s ski mask

The bank robber’s ski mask is both a disguise and a piece of potential evidence in the apartment hostage crisis. Its changing use tracks the bank robber’s shift from concealment toward accepting responsibility, even as the people around her try to shield her from identification.

Concealment and Uncertainty

When Jim arrives with pizzas, a person in a suit and ski mask opens the door. The disguise makes the person’s identity uncertain; the account later clarifies that the real bank robber, not Lennart, opened it. The mask thus helps sustain appearances at the apartment door without ensuring that the bank robber can remain hidden from the people inside or from the police.

Removal and the Choice to Face the Consequences

Alone in the hall, the bank robber removes the mask as she considers what will happen when the hostages leave and she is recognized as the criminal. She understands that the disguise can no longer offer a way out, and her attention turns to the pistol in her hand. Zara intervenes before the bank robber can act. Later, Roger and Lennart both want to wear the mask, but the bank robber refuses. She explains that, since she cannot set a good example by avoiding responsibility, she can at least show her daughters how to take responsibility for her actions. When Jim returns, she opens the door without the mask.

Cover Story and Destruction

The hostages propose telling the police that the bank robber never removed the mask, so they cannot describe her. This planned account would use the mask not merely to obscure her face but to conceal that she had revealed it to them. After the hostages leave, the bank robber burns the ski mask because Roger warns that the police could recover DNA from it. The act removes an object that might identify her, even as her earlier decision to open the door barefaced marks a willingness to accept responsibility in front of Jim.
