Call it “7 Seconds in Heaven.” Below is the first footage of Marvel’s Agents of S.H.I.E.L.D., which will have its full preview tonight (30 seconds) during ABC’s Once Upon a Time finale. The ultra-brief footage includes a look at resurrected Agent Coulson (Clark Gregg), who doesn’t look too pleased about something (being killed off in The Avengers, perhaps?). ABC is also suggesting the hashtag #CoulsonLives, which makes sense — nobody wants to type out all those periods in #S.H.I.E.L.D. and #MarvelsAgentsofS.H.I.E.L.D. would practically use up an entire tweet.
