Sitwell, like most of the S.H.I.E.L.D. leadership at the time, is seemingly killed by a self-aware, renegade "Deltan" variety of S.H.I.E.L.D.'s artificial human "Life Model Decoys", and replaced by one such LMD, which was then installed as Executive Director. The real Sitwell later turns up alive after having been brainwashed by a faction of the terrorist organization HYDRA, placed in suspended animation, released as part of a plot against Fury, and eventually deprogrammed. He has since become S.H.I.E.L.D.'s top interrogator, often paired with fellow agent Jimmy Woo. He has also worked closely with G. W. Bridge, mainly in an attempt to neutralize the threat of the Punisher.
