After a rocky start, Agents of S.H.I.E.L.D. has since found its way. Although it still has not been fully embraced by fans, the series has made great strides over the past two and a half seasons. Marvel seemed to loosen the reigns on the show after Captain America: The Winter Solider, which is what has led us to getting a fourth season – something that would not have seemed likely in 2014. The show is slated to have a panel at SDCC tomorrow with plenty of the cast being in attendance.

What could come out of the panel remains unclear outside of come new additions to the cast or teasing the arrival of new characters, similarly to what they did with Mockingbird. Now, there is an outside chance that we could actually see something from season 4. Members of the Agents of S.H.I.E.L.D. team have taken to social media to reveal that they have begun filming season 4 as of today.
