The Walking Dead season 11 is the final installment of the zombie post-apocalyptic drama. The series featured a lot of notable characters throughout its run, including Andrew Lincoln's Rick Grimes. He's been an essential part of the story, and there's a question whether or not he'll show up again.

Rick was a major character in the series, who was introduced in 2010. He's the one guiding the group in fighting against several villains -- including Governor (David Morrisey) and former-antagonist Negan (Jeffrey Dean Morgan). Now, is there a chance for him to return in The Walking Dead season 11?

Lincoln's return as Rick has been confirmed in the spin-off movie. However, it is unknown if he'll be appearing on the small screen before the series officially wraps up. He left midway through season 9 but left the door open for his comeback.

Rick was presumed dead by his group, yet it was revealed that he was secretly rescued by Anne (Pollyanna McIntosh). He was brought on the CRM's (Civil Republic Military) helicopter and took him to an unknown location to start a new journey.

The CRM was properly introduced in the series spin-off The Walking Dead: World Beyond. The group is being led by Elizabeth (Julia Ormond), and their arrival seemingly suggests that there's a chance for Rick to re-appear within the universe.

Fans have been wondering if the character is coming in The Walking Dead season 11 -- or in the spin-offs The Walking Dead: World Beyond or Fear The Walking Dead. That remains a question for now, though some spotted his presence in the Thanksgiving photo shared by the flagship's official Twitter account.

The portrait features several of the leading characters -- such as Negan, Carol (Melissa McBride), and Daryl (Norman Reedus) -- celebrating the Holiday. Other notable characters were also present, such as Maggie (Lauren Cohan) and Judith Grimes (Cailey Fleming).

But, what makes the photo a bit intriguing is that an unidentified figure on horseback was seen far in the background. Then, three helicopters can be seen hovering above him and the group, prompting fans to speculate that these belong to the CRM.

It wasn't officially confirmed that the mystery rides is Rick, but fans were convinced it's him considering his exit in season 9. Some noted that this is a clue to tease his potential return in The Walking Dead season 11. Also, it is a confirmation that he's still part of the group despite him being away from them.

One fan believes that it may be Rick on the horse, while another one says they can't wait to see the character reunite with his kids and partner. However, others think that the mystery rider is a red herring, and it could be Virgil (Kevin Carroll).

For now, fans have to wait and see if Rick is, indeed, making an appearance in The Walking Dead season 11. At the moment, the final installment is far from premiering since the six bonus episodes of season 10 were needed to be aired first.
