The Walking Dead Season 7: 7 Things You Missed In Episode 6
3. The PPP
Probably the most intriguing nod to the future is Tara unearthing a key card with the initials PPP inked on one side. There's no way of guessing from what fans have already seen but the show will be exploring the PPP in future episodes.
Actress Alanna Masterson spoke on Talking Dead about not even knowing what the letters mean, which offers little hope for everyone else.
She claimed that the only man in the know is showrunner Scott Gimple. Time will tell whether the letters have any great significance on the story or just another red herring.
