ABC and Marvel may have been teasing us for months with footage from the 'Agents of S.H.I.E.L.D.' September 24 premiere, including the recent round of clips, but we've also seen a few glimpses of the episodes to come. Now, we've got our first details of followup episode "0-8-4" set for October 1, so what new 'Agents of S.H.I.E.L.D.' mysteries are revealed?

According to ABC's officially press release for "0-8-4," the second 'Agents of S.H.I.E.L.D. episode will take us abroad as "Coulson runs into Comandante Camilla Reyes when he and the agents travel to Peru to investigate a mysterious object." That certainly fits with the jungle footage we saw in an earlier trailer, but what do we suppose the mysterious object might be? That pesky cube didn't fall to Earth again, did it? Another item of significance in the Marvel universe, perhaps?

While we await the September 24 premiere, we know that Marvel’s ‘Agents of S.H.I.E.L.D.’ features a cast that includes Clark Gregg as a resurrected Phil Coulson, Ming-Na as badass Melinda May, Brett Dalton as Grant Ward, Iain de Caestecker and Elizabeth Henstridge as Leo Fitz and Gemma Simmons, and Chloe Bennet as hacker Skye. ‘Ghost Whisperer’ vet David Conrad and ‘Luck‘ star Ian Hart have been added for recurring parts, though details remain light on their scientist roles, while Cobie Smulders is confirmed to return as Maria Hill for the pilot at least.

Samuel L. Jackson previously stated that he expected to be involved with the show in some small capacity, while Tom Hiddleston and Sam Rockwell are game to reprise their Marvel Cinematic Universe roles of Loki and Justin Hammer respectively, something we’ve analyzed the likelihood of in depth.
