Eddie saves Mary after Danielle pushes her out an upper story window. To protect Mary, Eddie agrees to Danielle's demand for more of the Fly drug. Then in a flashback, we see how Eddie introduced the Fly drug to Danielle shortly after her father's 'disappearance'. Back in the present, Eddie gives Danielle a drug that Francis said would negate the effects of the Fly drug permanently, but instead it kills Danielle.
