The Walking Dead Season 7: 8 Big Questions After 'Swear'
3. How Long Before Alexandria Finds Out About Oceanside?
Tara has a unhappy homecoming at the end of the episode, returning to Alexandria only to learn of Denise's demise (and that of Glenn and Abraham too).
It'd have been easy for her to give up the truth about Oceanside, since they did try to kill her. So it's a testament to her character that she lies to Rosita, saying she didn't find anything on her trip.
This being The Walking Dead, though, it's highly unlikely that'll be the end of it. A new community isn't going to be introduced and then left to its own devices. Will Tara come clean eventually? Will someone else come across Oceanside? Or will one of their members come calling to the Safe Zone for help?
