With episodes cutting back and forth in time and character groups splitting off as quickly as people usually die, “The Walking Dead” has been difficult to comprehend in the first half of the fifth season. Previews of the first few episodes of the rest of the season forecast a dark and twisted plot line. So, with the midseason premiere coming up this Sunday, it’s important to go back to the first half of the season and lock down the events in our memories because it’s going to be an intense ride for the rest of the season. Or if you’re behind and just couldn’t find the time to finish off those last episodes before the show’s winter break, you can easily catch up with these key plot points (spoilers ahead, obviously).

Beth died.

After a long plot sideline in the Grady Memorial Hospital, Beth (Emily Kinney) was killed in a symbolic act of violence against the regime’s manipulative leader, Dawn. Beth matured into a strong, independent, useful-in-a-post-apocalyptic-scenario character during her time at the hospital. The Beth that stabs Dawn in the shoulder with scissors in the midseason finale is very different than season-two Beth, who considered suicide because coping with the apocalypse and her family’s deaths was too difficult. Many fans refused to accept Beth’s death, and currently a petition with over 62,000 supporters demands for the show’s producers to bring Beth back in some way. Who knows? Maybe Beth will be back during the second half of the fifth season.

Noah joined the crew?

Beth’s fellow Grady Hospital prisoner, Noah (Tyler James Williams), escapes the face-off alive. Even though he helped Rick and the crew find Beth in the end, he got a rough start with them by trying to rob and set walkers on them. Despite rocky beginnings, there are hints that Noah might be initiated into the fold.

Turns out Eugene isn’t a scientist.

In an impassioned moment, Eugene reveals to half of the group that he isn’t a scientist and that everything he has told them about Washington, D.C., is a lie. Finding a cure has been motivating the characters for a while, casting a hopeful tone on the often bleak and dreary show. Undoubtedly the rest of the show’s cast will definitely experience philosophical doubt in the second half of the season, especially since some of the characters have yet to find out about Eugene’s confession.

Father Gabriel faces reality.

Unable to face the dangers of the outside world for most of the fifth season, in the last moments on screen that he’s given before the D.C. group comes back, Father Gabriel realizes the dangers of his actions as he brings a walker crowd back to the church, where Michonne, Carl and Judith are waiting. His use of the machete to escape the church showed that he wasn’t ready to face violence yet, and he’ll have to overcome that conflict of morality in some way in the second half of the fifth season if he wants to stop jeopardizing the lives of the people around him.

Morgan is still following them.

Remember the father from the first episode who helps Rick out, later goes crazy and barricades himself inside a labyrinthine house? He’s been following the cast for all of the fifth season, and he still hasn’t made contact with anyone. Hopefully this will be explained in the second half of the season because it’s starting to get a little creepy, and answers about his identity and just why he’s following the group need to be answered.

Now that we’re all on the same page, you should be ready to jump right into the mid-season premiere of “The Walking Dead” at 8 p.m. this Sunday on AMC.
