MARVEL'S AGENTS OF S.H.I.E.L.D.
ABC, 8:00 p.m. ET
Part 2 of this galactic showdown has the S.H.I.E.L.D. crew hamstrung, and seemingly helpless, against Sarge, who may help them save the planet – but at a very significant cost. And the fact that this big bad villain, who has no problem threatening them at gunpoint and even shooting them, looks exactly like their former, heroic boss.
