The Walking Dead episode 816: Things To Note from Wrath
By Liam O'Leary
1) The pseudo-flashback Rick has to him and young Carl walking together along a country road is the first time we’ve seen Rick in his Sheriff’s uniform since he “retired” it on Hershel’s farm way back in Season 2.
2) When Rick asks Siddiq about Carl’s death, Siddiq begins by recounting the circumstances of his mother’s death. This is the first time we’ve heard this story since meeting Siddiq in the Season Eight premiere episode, “Mercy”.
3) Siddiq refers to the dead as “The Monsters”. While I doubt this is the first time walkers have been called that it may be the first time it’s been used officially as a name for them. If so, this would make the…twenty-first(?) unique name for the dead.
4) Siddiq telling Rick that “All we have left of the dead…are there ideas” is some preeeeeeeety big foreshadowing for those who haven’t read the comics.
5) Morgan’s words to Rick, “We are than we were…me and you.” may confirm that when he said to Rick “everybody turns” after the two of them slaughtered Jared and the rest of the Savior escapees back in the season’s fourteenth episode, “Still Gotta Mean Something”, he was meaning that everybody turns into a killer.
6) Additionally, Morgan telling Rick “We can’t go back” is a phrase the became something of a theme for much of Season Five of The Walking Dead, first being said to Bob Stookey by Gareth in the Season Five opener, “No Sanctuary”, when, after hearing Bob telling him that Eugene had a cure, Gareth simply shrugged Bob off and told him, “You can’t go back, Bob”.
