Warning: Spoilers ahead for Marvel's Agents of S.H.I.E.L.D.
ABC and Marvel Studios have released promotional photos for the upcoming, April 15 episode of Marvel's Agents of S.H.I.E.L.D., titled "Providence." In the episode, Coulson squares off against Colonel Glenn Talbot and what appears to be a revitalized Centipede, with some major spoilers taking place in the photos below the jump. Back when Raina was arrested by S.H.I.E.L.D., we and many others speculated that perhaps the knowing smile she shot Coulson as Victoria Hand took her away suggested that Centipede had infiltrated S.H.I.E.L.D. and Raina would be out of jail sooner than later. Apparently, not only were we right but both John Garrett and Ian Quinn will join her, along with what looks like one of the Graviton devices from early in the season. Add to that Glenn Talbot (Adrian Pasdar) and Eric Koenig (Patton Oswalt) and you've got quite a lot going on in these photos... "Providence" - With Colonel Glenn Talbot now on their trail, Coulson and his team seek refuge in the last place anyone would look, where they begin to uncover S.H.I.E.L.D.'s most dangerous secrets--secrets that could destroy them all, on "Marvel's Agents of S.H.I.E.L.D."
