Raina

"We would like you to touch base with The Clairvoyant. See if any insights can be given... on Stage Three." "The Clairvoyant doesn't like to be touched." "We all have to do things that make us uncomfortable, if we are ever to get our toy soldiers off the shelf."

- Raina and Edison Po

Raina is a recruiter who works with the mysterious organization behind the Centipede Device. She recruited Michael Peterson to be a test-subject for the Centipede process, and she kidnapped Chan Ho Yin in order to use his pyro talent to make the volatile Extremis elements safe. She used the the Theta Brain-Wave Frequency Machine on Agent Phil Coulson to make him remember how he was brought back to life. After Skye tracked Coulson down, she was arrested by S.H.I.E.L.D. and imprisoned in the Fridge.

Biography
Raina worked for the unknown agency behind the Centipede process, mainly as a recruiter due to her persuasion skills.

Hong Kong
"You need a simpler name. A more powerful name. A name like Scorch." "Scorch? Are you joking?" "Have you ever heard of Steve Rogers? No? But Captain America-- now he's on the news, on a lunch box, on a poster on the wall."

- Raina and Chan Ho Yin

She contacted Miles Lydon about the retrieval of information about a super-powered pyrokinetic, a Hong Kong native named Chan Ho Yin.

She approached Chan in Hong Kong, and after talking her way into his apartment, abducted him for her mysterious employers. Working with the doctor known only as "Debbie", who was attempting to stabilize the Extremis element of the process, Raina assisted in the harvesting of the fire-proof platelets in Chan's blood that kept his power from burning him alive. After getting what they needed from Chan, he was scheduled to have all of his blood drained from his body.

Before that happened, Chan escaped and confronted Raina and Debbie. Raina closed the elevator door that separated her and Debbie and escaped, saving herself, leaving Debbie to be incinerated by Chan.

Raina was later seen visiting a prisoner named Edison Po at the Havenworth Federal Penitentiary. She informed Po that with the stabilization of the Centipede process, "Stage One" of the project had been completed and that they were moving into "Stage Two". She then asked Po to contact someone known only as "The Clairvoyant" for their mutual employers for any insights he might have as to "Stage Three".

"Will you tell me what he's like?" "Never. The last person who tried to learn such things got a knife for it. I don't want to have to do that again, Raina. You have such pretty eyes." "I understand. You can't even whisper to me about him." "No, I can't."

- Raina and Edison Po, speaking about the Clairvoyant.

Soon after, Centipede arranged for Po's escape. Raina was next seen in Oakland, California, assisting Po and bringing him up to date on the project's progress. Raina inquired about the nature of the Clairvoyant to Po, who was adamant in not revealing any details about him.

Raina assisted Po in setting up an unsuccessful ambush on the S.H.I.E.L.D. unit under the command of agent Phil Coulson, where Po realized that Coulson and his mysterious return from the dead was the key to Centipede's plans. Later, at Po's direction, Raina kidnapped the son of S.H.I.E.L.D. trainee and Centipede test-subject Michael Peterson in order to bring about another confrontation.

At the meeting, Peterson betrayed Coulson to Raina in exchange for the safe return of his son. Raina escaped by helicopter with Coulson to a location in the Mojave desert.

The Mojave Desert
"You didn't just give your life, you gave up your chance at a normal one, at love. And she did love you, Agent Coulson." "How could you know that?" "Do you miss her? Dinners at the Richmond. Do you miss hearing her play? You didn't even have a chance to say goodbye." "I couldn't... I can't..." "She cried for days after S.H.I.E.L.D. told her you died. They shattered her heart with a lie, and now they're lying to you." "No. No they're not." "I know you don't want to believe it, but you can't tell me nothing makes you doubt, makes you wonder what happened in Tahiti."

- Raina and Phil Coulson, the former attempting to win the latter's trust. At the Centipede site in the Mojave Desert, Po worked on interrogating Coulson, using a Theta Brain-Wave Frequency Machine designed to unlock hidden memories, while Raina saw to the recovery of Michael Peterson, who survived an explosion set by Centipede back in Long Beach. This lasted until the Clairvoyant grew impatient with Po's progress and killed him, giving Raina the job of finding out Coulson's secrets.

Through persuasion and emotional manipulation regarding Coulson's former lover, Raina convinced Coulson to not resist and let the machine do its work. While Coulson was under the machine's influence, his team arrived to affect his rescue. Raina was incapacitated by Skye, and taken into S.H.I.E.L.D. custody.

That S.H.I.E.L.D. was able to take Raina into custody alive would indicate that she was not outfitted with a Backscatter X-Ray Eye Implant.

The Hunt for the Clairvoyant
Agent Skye asked Coulson if, during his time in the Mojave Desert, Raina mentioned the death of his father. Skye had found that information in Coulson's psychological profile; it was called "a defining moment" in Coulson's life. Correlating the two caused Coulson to realize that the Clairvoyant is a S.H.I.E.L.D. agent.

Arguing with agent Coulson about why Victoria Hand should be killed instead of sedated if she was the Clairvoyant, Agent John Garrett said that Coulson and Raina were both subjects of the Theta Brain-Wave Frequency Machine, a fact that Coulson revealed to no one. This knowledge led Coulson to realize that Garrett was the Clairvoyant.
