Infiltration into St. Louis Aerospace Facility

The Infiltration into St. Louis Aerospace Facility was an attempt by Ruby Hale and team Sleeper Mechs to kill S.H.I.E.L.D. agents.

Background
After abduction of her allies, agent Piper was captured by General Hale who forced Piper to make a deal to betray her friends and have them arrested, with Hale promising their safety. Using the Kree Orb, Piper tricked the S.H.I.E.L.D. agents into investigating as she claimed to be there to investigate the Kree Orb herself.

When the team returned from the future, they learned about beams of light coming from space onto Earth, similar to what Samuel Voss mentioned to Phil Coulson. They decided to investigate the place. The team arrived to the River's End and found Zephyr One. Aboard the Zephyr, Leo Fitz and Jemma Simmons discovered that the light beams are not what they look like and identify their origin: the Kree Orb used by Hive at Union City.

Infiltration
The team infiltrated the St. Louis Aerospace Facility, where they found Piper, who told them that she is also here to investigate and try to deactivate the Kree Orb. Piper told that she looked for them, but to no avail, while eluding the authorities. Fitz and Simmons discover that the Kree Orb was rigged with a timer to regularly activate it. At this moment, group of Sleeper Mechs led by Ruby Hale appered in the facility and confront them. While Piper held her gun to some of the agents, Ruby and her soldiers stepped into the room and held their guns to them, while Piper insisted that Hale had guaranteed the agents' survival. However, Ruby quickly realised that Quake was not present in the room and therefore ordered her soldiers to kill all of the agents. Before the mechs could open fire, Yo-Yo Rodriguez used her power to disarm the soldiers before she and the other agents charged into battle against them. Ruby took a step back as she watched her soldiers fighting against the agents, with Alphonso Mackenzie eventually shooting one of them in the face and discovered that they are machines. Upon seeing Ruby's betrayal of her trust, Piper changed side and assisted the agents with getting the Orb out of the facility while the other agents continued fighting the remaining robots.

Ruby waited for the ideal moment as she watched Mackenzie and Rodriguez both getting held back by the soldiers, knowing that they would run to each other's aid in a moment. Once Rodriguez freed herself, Ruby then drew one of her Ring Blades and waited for Rodriguez to use her power to save Mack. Ruby threw her blade and successfully sliced through Rodriguez's arms. Agent escaped from the facility n Zephyr One and Ruby let them go.

Aftermath
Agents brought Orb to the Lighthouse and contained it in the room with Monoliths. Leo Fitz and Noah were checking on the Orb. When Johnson entered the room, Noah noticed that the circuitry were heating, so he covered the Orb with his body to defend the two from the explosion. Explosion destroyed White Monolith, Grey Monolith and Black Monolith and created Rift to the Fear Dimension.
