Without more context, it's challenging to provide a detailed response. However, I can offer some general information about Eyeless Jack and the nature of creepypastas:

The original 2012 story, posted on the Creepypasta Wiki , is a masterclass in anti-climax. The narrator wakes up to find a figure leaning over his bed. Jack doesn't chase him. He doesn't monologue. He simply reaches into the narrator’s side, removes the organ with "surgical precision," and leaves behind a single, black, gelatinous capsule to stop the bleeding.

Other versions depict him as a former medical student or soldier who developed an insatiable taste for human flesh, specifically targeting the nutrient-rich kidneys [2].
