The short version
Liz — Lisbeth, per the community wiki — is a caracal with light brown fur and downturned dark ears, and one of the game's late-shift lore characters. Her backstory is the sharpest lore hook in the cast: she is a former hospital employee fired for reporting what the company called fake news. The wiki's update log lists her appearances in Shifts 10-21, and July event coverage from the Harlow's Favorite Update connected her to a UV camera task with named-patient photography and reported trust consequences for mistakes.
