Though a second season remains somewhat in limbo, Marvel's 'Agents of S.H.I.E.L.D.' continues building up to the big time of its first season finale in tomorrow's "Nothing Personal," bringing in 'Captain America: The Winter Soldier' star Cobie Smulders to reprise the role of Maria Hill. Yet another sneak peek from the hour has arrived, but this time with the surprise bonus of Marvel's Man-Thing, and an appearance from Pepper Potts! Sort of!

Our latest look at Marvel's 'Agents of S.H.I.E.L.D.' picks up with Maria Hill in the wake of her own testimony before Congress, updating her new boss Pepper Potts over the phone on everything from the Fridge, to the mysterious Man-Thing. Melinda May steps in for a word, and the two get down to business on Fury's cover-up of Coulson's new alien friend, Stark Industries privatizing world security, and the former director's supposed "death."

Here’s what ABC had to say of next week’s “Nothing Personal”

“Nothing Personal” – Just when there’s no one left to trust, Agent Maria Hill (Cobie Smulders) — from “Marvel’s The Avengers” and “Marvel’s Captain America: The Winter Solider” — returns to team up with Coulson as S.H.I.E.L.D. is being destroyed around them.

Guest starring are J. August Richards as Mike/Deathlok, Cobie Smulders as Agent Maria Hill, Adrian Pasdar as Colonel Glenn Talbot, B.J. Britt as Agent Antoine Triplett and Josh Breeding as parking attendant

It's tough to say where Maria's loyalties lie, given the last sneak peek we saw of "Nothing Personal," but what do you think? Will Maria's appearance make tomorrow's episode the most Marvel-ous to date? Watch the sneak peek below, and give us your predictions in the comments!
