According to Design N Trend, the season 6 finale scene with Tara and Heath featured several walkers and this suggests that their original plan didn't go as expected.

In the end, lurkers spotted a similar-looking RV heading towards Alexandria. But it isn't clear whether or not this is still Tara and Heath's vehicle.

Meanwhile, even though not many details have been released by the spoiler site, the publication claimed that episode 6 will focus mostly on Tara's character development.

Other than Tara, the other characters that will be featured in the episode include Carl, Rosita, Eugene and Enid.

This report also shuts down rumors that Eugene or Rosita could have been Negan's (Jeffrey Dean Morgan) victim from the season 6 finale.

At present, the only character that hasn't been spotted on set is Glenn (Steven Yeun).

In other news, "The Walking Dead" season 7, episode 6 will also introduce two new characters who will be arriving in Alexandria with very different missions.

One of the characters is a grandmother named Naomi and the second character is a young lady named Jennie.

The publication is speculating on the possibility of the two characters being part of Tara's past instead of the present-time in Alexandria.

With this, one can assume that the upcoming sixth episode this season can be considered as a bottle episode that is expected to serve a purpose.

After all, this isn't the first time that the producers of "The Walking Dead" introduced such episode throughout the first six seasons.

Last year, an entire episode was focused solely on Negan and another episode revealed more information about Enid.

As of late, it is still unclear whether or not Tara is the only character that will have such an episode in the series.

"The Walking Dead" season 7 will premiere on AMC starting Oct. 9.
