Plot
As Dum Dum Dugan attempts to recruit Peggy Carter into S.H.I.E.L.D. they run into Lady Sif.

Reception
Jesse Schedeen of IGN expressed that the idea of the teaming up Peggy Carter with Lady Sif is an appealing concept but that unfortunately, the issue doesn't end up using the novel team-up to very good effect. Doug Zawisza of CBR.com stated that while the one-shot is a decent tale the art is where it struggles, mostly from a storytelling perspective. He says that the artist, Ellis relies on action lines to tell the tale rather than the characters themselves and that the decision to keep the beret, necklace and earrings on Carter undermines the severity of the plot.
