Warning: Spoilers ahead.

The Marvel universe has no bounds; it spans both the small and bigscreen.

ABC's "Marvel's Agents of S.H.I.E.L.D." will be rocked by the fallout from Disney-Marvel's "Captain America: The Winter Soldier" come Tuesday. Following the film's reveal that the terrorist org HYDRA is still prospering, this week's tie-in episode will find the agents turning on each other as there's no telling who infiltrated S.H.I.E.L.D. as a HYDRA mole.

ABC posted a sneak peek of the upcoming episode, "Turn, Turn, Turn," on its Facebook page featuring an armed confrontation between Coulson (Clark Gregg) and May (Ming-Na Wen). In the clip, Coulson suspects that May has betrayed the group by rerouting Garrett's (Bill Paxton) plane, while she insists she had nothing to do with it and is reporting to Fury. Like "Captain America's" Maria Hill (Colbie Smulder), May could be one of the few agents still loyal to the director.
