During this week's "Agents of SHIELD" episode, Patton Oswalt returned as everyone's favorite family of Koenig brothers and Radcliffe got his hands on the Darkhold. Coulson also discovered that Agent May had been replaced by a Life Model Decoy. This news came as quite a shock, considering Coulson and May had just shared a kiss together.

Back at the SHIELD base, the LMD bodies of AIDA and Radcliffe were burned, but not LMD May. Perhaps Coulson is hoping to glean some information from her regarding the whereabouts of the real Agent May. When the series returns next week for "Boom,"  Coulson and Mack will embark upon a recovery mission to find her.
