“Marvel’s Agents Of S.H.I.E.L.D.” Season 2, episode 9, brought out all the drama. Searching for Coulson’s mysterious city put the team in danger, and someone didn’t make it out. Ward (Brett Dalton) returned to take one of the team members hostage, and someone ended up getting possessed by an alien.

The episode started with Skye’s nightmare. Skye (Chloe Bennet) was running through the hall in a flower dress (which looked more like it belonged to Raina). She was abandoned in the S.H.I.E.L.D. facility and could only hear a sound like a music box. When she found the box, she saw Coulson (Clark Gregg). Then she saw Coulson with May (Ming-Na Wen) holding a baby.

“Sacrifices have to be made. Poison tree, poison fruit,” May said.

Skye touched the music box and started to turn to stone, the same effect the obelisk has on most people. Skye woke up and tried to shake off the dream. She had to gear up for a big mission.

Coulson explained that the team was going to the mysterious city from his drawings. It was located under San Juan, Puerto Rico. They needed to get to the temple in the city before Hydra. Coulson explained that the obelisk was a key and a temple was the lock. If Hydra brought the obelisk to the temple, it might unleash a weapon of mass destruction. Luckily, S.H.I.E.L.D. found the city first, but they had to get to the temple and destroy it.

Of course, S.H.I.E.L.D. can’t focus on just one problem at a time. Raina (Ruth Negga) returned when Hydra came after her. Raina saw May in a café and approached her. However, her face was damaged, with a huge portion burned. It wasn’t May, but a Hydra agent sent by Whitehall (Reed Diamond). It was Agent 33, still wearing the mask May damaged in episode 4.

The Koenig brothers (Patton Oswald) helped her escape using an invisibility umbrella.

Back on the bus, May and Skye saw the news footage of Senator Christian Ward’s house on fire. They knew Grant Ward killed his brother. They couldn’t focus for too long. They had to extract Raina, meaning they couldn’t go to the city. May knew Coulson didn’t want Skye in the city.

“It’s not the city I’m afraid of,” Coulson said. “It’s her lunatic father.”

In the lab, Bobbi (Adrianne Palicki) seemed less worried about imminent danger and more interested in Simmons (Elizabeth Henstridge) and Fitz’s (Iain De Caestecker) past. She thought they were romantically involved, but Simmons explained that they weren’t. She said that he admitted his feelings for her before his injury, but she only saw him as her best friend.

“I never thought of him as anything else,” Simmons said. “That said, I couldn’t imagine my life without him.”

Bobbi told her to be honest with him, but she isn’t taking her own advice. Bobbi is hiding something from Hunter (Nick Blood). Mack (Henry Simmons) referred to it as “the other thing,” and figured she would tell him “after Hartley.”

While Bobbi drove a plane to Puerto Rico, Skye went to pick up Billy Koenig and Raina. Agent 33 -- with May’s face -- attacked. Skye offered to help her, but 33 was brainwashed by Hydra. She didn’t think she needed help, and Hunter took her down.

While they were on the run, Raina was told that Hydra had the obelisk and they wanted to use it. Raina realized that Hydra didn’t want to kill her if they had the obelisk. They needed her. Raina said she could touch it because she was worthy, and she explained that Skye could touch it too.

“You wouldn’t [turn to stone],” Raina said. “Not according to your father. He believes you’re worthy too. … It’s not crazy. It’s our destiny.”

Raina wanted to help Hydra. She tried to get the attention of Hydra agents, but S.H.I.E.L.D. tossed her in a van. Unfortunately, she managed to tell Hydra that she had a tracker in her during her confrontation with Agent 33. They knew how to find her.

In Puerto Rico, Bobbi wanted to make sure that Coulson wanted to destroy the weapon. Fury (Samuel L. Jackson) would want to recover it. He would also have a number of “acceptable losses” but Coulson wasn’t Fury.

Fitz, Mack and Simmons were still on the plane getting all of their tech gear ready. “The awkward silence in here is killing me,” Mack said.

Fitz and Simmons finally confronted each other. Simmons tried to tell him that her leaving had nothing to do with him, but Fitz interrupted to tell her that he was leaving the lab. He wanted to transfer. “You know why,” he said. “You’re clearly far more capable than I am. … I can work for you, I just can’t work with you.”

It seemed that their last mission together would be in a tower that was known as being haunted. Fitz and Mack opened up the floor to find that they couldn’t see the bottom. They sent drones down, but they went offline. They would have to go down there in person.

After they got Raina on the plane, she explained that Skye’s father was “misunderstood.” She was working as a con artist when Skye’s father took her in. She claimed he gave her a purpose. She asked Skye if she ever felt different or special.

“When you say special, what you really mean is alien,” Skye said.

“We’re human, Skye,” Raina said. “We just have the potential to be more.”

Raina explained that her grandmother believed a story about blue angels who came down to Earth. “The ancients called them the Kree,” Raina said.

The Kree left the obelisk so the worthy would inherit the earth. The unworthy wouldn't be well received.

Skye wanted to pull Coulson and the team out of the tower, but she had no signal when she called. Whitehall used Raina’s tracker and had them surrounded. He wanted Raina. Ward walked onto the plane and said he was there to take Raina to Whitehall.

“Pick a side,” Skye said.

“Oh, don’t worry. I have,” Ward said.

He was taking Raina and Skye with him. He promised not to hurt anyone if Skye went easily. She had to go.

Unfortunately, she couldn’t warn the team not to send anyone below ground. Mack was sent down first. He traced a small circle, part of a carving that looked like Coulson’s drawings. Then he screamed out in pain. They pulled him up; his eyes went red, and he said in a deep voice, “Run.”

He tried to strangle Bobbi, and the icer gun didn’t do anything to him. When he didn’t react, Coulson tried to choke him, but Mack flipped him onto the ground. Simmons tried to hit him with a case, but he tossed her aside. She almost fell down into the hole, but Coulson grabbed her ankle. Fitz was ready to shoot Mack, but Bobbi electrocuted him. He reacted, but he fell down the opening in the floor.

Coulson demanded that they seal the floor without saving Mack.

“What about Mack?” Bobbi said.

“That wasn’t Mack.” Coulson said.

Hydra’s plans didn’t go well either. Apparently, Skye being a hostage wasn’t part of the plan, but Whitehall didn’t seem to mind. Letting the plane go free wasn’t part of the plan either, and that made Whitehall angry. They were supposed to shoot down the S.H.I.E.L.D. plane no matter what. Agent 33 called the plane and told them to take down the team’s plane.
