Battle of Chicago

"I need to arm myself so I can fight my enemies." "You are becoming the enemy. Whether you believe it or not."

- Glenn Talbot and Quake

The Battle of Chicago was a confrontation between S.H.I.E.L.D. and Glenn Talbot, in order to stop him from infusing himself with the Gravitonium located under Earth's surface, which would cause the prophesized destruction of the planet.

Background
"He tells me there's untapped deposits of Gravitonium under the Earth's surface." "And you want to get it out and power yourself up more."

Battle
"This is S.H.I.E.L.D.., we're here to help. We have an aircraft to evacuate any civilians trapped near the center of the city, you'll know it when you see it. Get them there. We will clear the high floors of the impacted buildings before they collapse. And most importantly, do not engage the enemy. I repeat, do not engage the enemy. We will handle it."

- Alphonso Mackenzie to the civilians of Chicago

S.H.I.E.L.D. arrived in Chicago, Alphonso Mackenzie being appointed as leader. Mackenzie then made an announcement to the civilians of Chicago to head towards the Zephyr One and to not engage Glenn Talbot.

Jemma Simmons, Yo-Yo Rodriguez and Piper assisted in the evacuation, while Mackenzie, Melinda May and Leo Fitz went to find Polly and Robin Hinton, and Quake went to fight Talbot. Quake fought Talbot briefly, but soon attempted to convince him to stop, rather than kill him. Mackenzie, May and Fitz found Robin, but her mother was still trapped in Qovas' Ship, so Mackenzie went in to find her. Fitz then realized that neither Mackenzie or Polly make it in the future, so May and Fitz went in after them. Two Remorath attacked Mackenzie and nearly defeated him until May helped him and she and Fitz killed the Remorath. When it seemed that Quake had gotten through to Talbot, he grabbed her and attempted to fuse her into him.

This resulted in some rubble falling on top of Fitz, ultimately killing him. Quake then discovered the Centipede Serum in her gauntlets that Coulson placed there. She injected herself with the serum and with the extra boost, quaked Talbot into space, killing him.

Aftermath
"He'll be so happy to know that time is not fixed. It's a fluid, ever-changing, beautiful thing. And he didn't miss much, did he?" "I have not a single doubt you will find him."

- Jemma Simmons and Phil Coulson
