“Hot Potato Soup”

We get a full family reunion of the Koenigs, Billy, Sam, Thurston and LT. They were whom Coulson trusted the Darkhold to in an attempt to keep it hidden.

Of course, Billy gets captured and Radcliffe heads into Billy’s mind to discover where it was hidden.

Patton Oswalt played three of the Koenig siblings… all except LT who was a sister.

The Darkhold winds up in Radcliffe’s possession at the end and the Shield agents finally figure out that May is also an LMD.

Radcliffe and Nadeer want the Darkhold to get rid of all the Inhumans.
