'House of Cards' Season 5: What We Know So Far

According to Daily Star UK, there have been strong speculations that Zoe Barnes might come back. A Twitter post from "House of Cards" the official social media account started the buzz around the character's return.

In the said Twitter post, a smiling Zoe was made into a GIF photo. This post made the netizens asking whether this is a clue or not. The fans started to flood the comments section with the possibilities on how the character will come back to the show and what will be her role in Frank and Claire's lives now.

However, setting aside these theories, a fan noted that the account has been posting a GIF episode almost every day and maybe it is only a "countdown" for "House of Cards" season 5 spoilers and premiere on May 30.

Come to think of it, the post has a caption "Chapter 4". Other commenters pointed out that the GIF is not a teaser but a cut scene from the previous episode. Meaning to say, there is a high possibility that Zoe's comeback is not true at all. The character is already dead unless an another expected and overused twist will happen to the series -- either she has a twin or she faked her death.

On a different not, let us not close the door to other possibilities. Though the clip in "House of Cards" official Twitter account is clearly a cut scene from the show's "chapter 4", maybe there is something more behind this GIF post.

'House of Cards' Season 5 Spoilers: Doug Could Be Frank's Killer

Doug is certainly the most loyal staff of Frank Underwood. However, it seems like the character will also leave the president's side, he might betray the president. With Zoe's zero to none chance of coming back from the dead, this will be another disappointment for the fans (if the predictions are true).

In Mahershala Ali's (Remy Danton) previous interview with The Wrap, he reveals his thought of who might kill the president. There have been speculations that it will be none other than Claire but with the actor's idea about this certain story arc, it turns out that maybe the killer would be someone Frank truly trusted.

The actor pointed out that a friend might kill Frank, "Like maybe at some point because he's the one closest to him, my guess would be [Doug] Stamper."
