The individual locked in Elliot's attic was Isla, a young woman whom Elliot had initially offered a place to stay.
The Circumstances Leading to Her Confinement
Isla's presence in Elliot's attic was not by choice, but rather a result of Elliot's desperate attempts to conceal his crimes. The sequence of events unfolded as follows:
- Initial Encounter: Isla was a young woman who had been rough sleeping when Elliot encountered her. He offered her a place to stay for the night, seemingly out of kindness.
- Drunken Confession: While Isla was staying with him, Elliot, in a drunken state, confessed to a significant crime: the killing of Sal.
- Attempted Escape: Upon hearing this shocking confession, Isla naturally attempted to escape the house, realizing the dangerous situation she was in.
- Forced Imprisonment: To prevent her from leaving and potentially revealing his secret, Elliot physically trapped Isla within the house and subsequently locked her up in his attic.
This act was a direct consequence of Elliot's need to silence anyone who might expose his involvement in Sal's death, turning a supposed act of generosity into a harrowing ordeal for Isla.
