Matheson's assassin kills Delancey and Root frames Scott Powell for the murder. However, John Reese intervenes and prevents Scott from being killed to complete the cover-up. With the help of "fixer" Zoe Morgan, Harold Finch figures out that Matheson was the one behind the killing. Morgan than approached Matheson at a vigil for Delancey, offering him her services and revealing her knowledge of what he'd done. Shaken, Matheson called Root who assured him she would handle it and to have his final payment ready. Unknown to Matheson, Finch was nearby using a forced pairing of Matheson's phone to record the conversation. After Reese killed Matheson's assassin, Finch sent the recording to Detective Joss Carter, exonerating Powell.
