Agents of S.H.I.E.L.D. - 4 x 14 - The Man Behind The Shield

[MS]

Interesting flashbacks of Coulson and May on a mission in Russia.
Shocking revelation when Fitz and Simmons discovered that Coulson, Mack, Mace and Daisy got replaced by LMDs.
Eerie that the episode ends with LMD Coulson waking up LMD May.
