The writer's room for Marvel's Agents of S.H.I.E.L.D. begins work on the upcoming season 5. The ABC series recently wrapped up its fourth season on the network, tying together three relatively disparate plot threads - broken down into "pods" - revolving around Robbie Reyes aka Ghost Rider (Gabriel Luna), Life Model Decoys like Aida (Mallory Jansen), and the simulated alternate reality called the Framework. Of course, the Agents of S.H.I.E.L.D. season 4 finale ended with a cliffhanger, depicting Phil Coulson (Clark Gregg) in some kind of spaceship after an unknown length of time.

A few days before the season 4 finale aired, ABC renewed Agents of S.H.I.E.L.D. for season 5, though it was later revealed the show won't return until the midseason point - making way for the network to roll out Marvel's Inhumans miniseries this fall. Agents of S.H.I.E.L.D. season 5 will debut in January of 2018, with no extended midseason breaks like those during season 4, and the writing team is already back at work planning for Coulson and company's next adventure.

A handful of writers on staff for Agents of S.H.I.E.L.D. took to social media to mark their first day back on the job for season 5, posting status updates on Twitter and Instagram. Those writers commemorating getting back to work include Nora Zuckerman, Drew Z. Greenberg, and Craig Titley. Plus, co-star Chloe Bennet (Daisy Johnson aka Quake) offered her own pitch for what she'd like to see next season. Take a look at their posts below:

First day back for the writers of #AgentsofSHIELD -- season 5 is alive!— Nora Zuckerman (@NoraZuckerman) May 31, 2017

All right, enough sightseeing. Get back to work. #AgentsOfSHIELD #writers #firstdayback #Season5 pic.twitter.com/RTy5ePk86L— (((DrewZGreenberg))) (@DrewZachary) May 31, 2017

Time to go to work #season5 #agentsofshield #writersroom #bestjobever #bestcastever #bestcrewever #youaintseennothingyet A post shared by Craig Titley (@craigtit741) on

My pitch: Daisy either needs a puppy or a boyfriend who stays alive/in this dimension. ? https://t.co/dqhDRfqA6v— Chloe Bennet (@ChloeBennet4) May 31, 2017

Of course, these social media posts don't give anything away about what the writing team - which also includes co-showrunners Maurissa Tancharoen and Jed Whedon among others - has planned for Coulson and his fellow S.H.I.E.L.D. agents. Last we saw of Coulson's cohorts, they had been eating a revitalizing meal at an unnamed diner following their battle against Aida and Ghost Rider's departure to destroy/hide the Darkhold. However, Coulson, Daisy, May (Ming-Na Wen), Fitz (Iain De Caestecker), Simmons (Elizabeth Henstridge), Mack (Henry Simmons), and Yo-Yo (Natalia Cordova-Buckley) were taken by what appeared to be government agents.

We do know that Agents of S.H.I.E.L.D. season 5 will include a time jump - likely between the diner scene and Coulson waking up on a spaceship - though it's unclear how much time will have passed. Additionally, with Robbie Reyes alive but elsewhere in the universe, it remains to be seen whether or not (and if so, how) Ghost Rider will appear in season 5 - or if the character will receive some kind of Agents of S.H.I.E.L.D. spinoff.

Still, with work beginning on the ABC show's next season, it's possible fans will learn soon enough what to expect from Agents of S.H.I.E.L.D. season 5 - perhaps even as soon as Comic-Con International in San Diego this summer. That is, after all, where Marvel revealed Ghost Rider would be joining the series for season 4. Marvel may have another big reveal planned for this year's SDCC, but with the show premiering later than usual, it's also possible fans will need to wait longer for any official news about Agents of S.H.I.E.L.D. season 5.
