Alex Trusk, under the alias Sasha, is a character in Cube 2: Hypercube.
She is a blind hacker, who fled into the Cube to escape from Izon operatives after realising Izon had been putting people in the cube and trying to blow the whistle on them.
Personality
She is shown to be a girl who is scared of loud noises, and seems to be a pessimist who says Continuously that "We're all dead".
Trusk carried a device on her neck (shown in the picture) that most likely contains top secret information about the Cube and/or its creators, until it was taken from her. Trusk was killed by Simon Grady, who snapped her neck after going insane from losing his grip on reality.
She is played by Grace Lynn Kung.
