Coulson tells the team that Hydra has the Obelisk as well as an expert who knows how to use it. There’s a powerful weapon inside the device. To activate it, they need to be inside a temple of a secret city that lies under San Juan. S.H.I.E.L.D. knows where this place is. Hydra doesn’t. They need to get there pronto to blow up the temple. Access the full Field Report for the "...Ye Who Enter Here" episode of Marvel's Agents of S.H.I.E.L.D. below. WARNING: There are SPOILERS here if you haven't seen the episode.
Do They Make Flowered Lanyards?: Daniel Whitehall’s followers, including a scarred Agent 33 (still looking a lot like Melinda May), track down Raina in Vancouver. Fortunately, a couple of Agent Koenigs (How many of them are there?) assure her escape through Sam’s use of a cool cloaking umbrella.
Skye’s the Limit: Coulson sends an extraction team consisting of May, Hunter and Skye. He doesn’t want the last agent mentioned anywhere near her lunatic father. Skye has other problems to deal with anyway.
Kree Fallin’: Raina tells Skye that her father is quite misunderstood. She claims she was a lost soul before she met him. She lets Skye know that the only thing her father wants is her. Raina further reveals that the Obelisk/Diviner was left so that the worthy would inherit the earth.
Relationship Issues: Mack questions Bobbi about her rekindled romance with Hunter. The two of them know something that Hunter doesn’t. Bobbi wants to keep it that way. Simmons opens up about what happened with Fitz and all the confused feelings she had since they were both left for dead. The two former best friends finally have a chat. It doesn’t go well.
Big Mack Attack: Mack is lowered into the area that leads to the secret city. He touches the ground to reveal an alien symbol. It glows red. The same alien symbol rises from Mack’s flesh. He’s in extreme pain. The team pulls Mack to the surface. His eyes glow red. He warns the others to run just before he violently lashes out at them.
Unscheduled Departure: Four QuinJets surround the cloaked airbus. Ward and a team of Hydra agents come aboard. They want Raina. Skye, too. If she doesn’t go, they all die. Skye assures May that she can handle herself. Raina reminds her bring along her tablet—the one with the map of the hidden city.
