"What Happened and What's Going On" is the ninth episode and mid-season premiere of the fifth season of the post-apocalyptic horror television series The Walking Dead, which aired on AMC on February 8, 2015.

It takes place 17 days after Beth Greene's (Emily Kinney) death as the group finds Noah's walled community known as "Shirewilt Estates", a nod to a similar location in the comic book series.

The episode primarily focuses on Tyreese, his struggle accepting death, and the guilt he faces over the losses of other group members due to actions he believes he could have done differently.

Several deceased characters return as hallucinations such as Martin (Chris Coy), Bob Stookey (Lawrence Gilliard Jr.), The Governor (David Morrissey), Lizzie and Mika Samuels (Brighton Sharbino and Kyla Kenedy), and Beth Greene.

The episode was lauded by television commentators, who praised Coleman's performance, Nicotero's direction, and Gimple's script.

The entire group makes the 530-mile journey to "Shirewilt Estates", a walled community outside of Richmond, Virginia, leaving Georgia behind.

Rick, Michonne, Tyreese, Glenn, and Noah decide to scout ahead and visit the compound first, while the others remain behind to be safe.

Tyreese tells Noah that he wanted to give in and die when Karen was killed, but that he kept on fighting, and decided to live and, as a result, he was able to protect Judith when she needed him.

Tyreese suffers severe blood loss and begins to hallucinate about news stories on the radio as well as visits by Martin, Bob Stookey, The Governor, the sisters Lizzie & Mika and Beth Greene, who discuss his actions throughout his time with the group.

Bob and the girls try to comfort and reassure him that he did the right thing, and that death is much better than being alive, but The Governor and Martin antagonize him for not being able to do what they feel needed to be done.

A visibly traumatized Sasha is seen struggling to stand throughout the service while Rick personally buries him and leaves his cap on his cross.

[7] The episode received critical acclaim, with many praising the direction of Nicotero, the script of Gimple and the performance by Coleman.

The critics' consensus reads: A visually impressive episode of The Walking Dead, "What Happened and What's Going On" artfully portrays the psychology of the characters, rather than focusing on its shocking moments.

He said, "It’s all of this attention to detail, whether just a terrific shot of the train tracks or a moment of explosive gore, that make this such a remarkable and memorable episode—an impressive cinematic achievement, and a tremendous hour of television.
