'The Walking Dead' star Katelyn Nacon helps us count down to the 100th episode

To celebrate the Oct. 22 Season 8 premiere of The Walking Dead — the series’ 100th episode — Yahoo Entertainment will be posting a new TWD-related story every day through the season opener.

The Walking Dead’s 100th episode is nigh, and our countdown to the big day continues, courtesy of Katelyn Nacon. The teen actress, who plays Enid on the hit post-apocalyptic series, took over Yahoo’s Instagram account as part of our 100-day celebration of the show, giving us a look at some of her favorite throwbacks, Disney memories, on-set study sessions, and even a selfie with her stunt double. Click through to see all of Katelyn’s photos from The Walking Dead set — and beyond.

The Walking Dead Season 8 premieres Oct. 22 at 9 p.m. on AMC.
