Between Fear The Walking Dead Seasons 3 and 4, the show went under a soft reboot and there have been numerous questions raised such as:
"what happened after the Dam explosion"?
"where is Daniel?"
"Did Taka make it to his people up North"?
"What happened to John and the Rest of the proctors?"
Among many questions.

In Fear Season 4, with Ian Goldberg calling the shots after Dave Erickson left, the show has a totally different feel and the first 3 seasons are almost skipable and it is overall a huge disrespectful middle finger to anyone who invested into Fear from the start.

There is also alot of confusion about how Dwight will cross over and alot of Fears about the show becoming too far gone from it's routes after Dwight joins the show.

I wrote this because I wanted to:
1. Bring EVERYONE back in a NATURAL (not contrived) way to bring closure to the fans and to also bring the old school FearTWD feeling back with interactions between old school characters.
2. Show the complete aftermath of the Dam explosion and explain the time jump.
3. Giving Morgan Justice as the new protagonist and giving Dwight a proper introduction that is logical.
4. Using Claudia as the glue to make it all work.

There are some Episodes that are total Fear episodes. There are some Episodes that are total TWD episodes. Some episodes have something exclusive. Others have a healthy mix.

P.S.-Fear Seasons 1-4 are a highly reccomended prerequisite, although it is not required per se.
