Iris West-Allen

Iris West is a waitress at Jitters and journalism student. She is also the daughter of Joe West, best friend and foster sister of Barry Allen, and the girlfriend of Eddie Thawne.

Early life
When Barry Allen was taken in to their home after his mother's murder and father's incarceration, Barry repeatedly ran away. One time when Joe went to get groceries, Iris allowed Barry to run away, refusing to tell her father exactly where to, despite him understanding the implication.

Living in Central City
After Barry entered a coma, Iris began visiting him frequently. She was said to talk a lot while at S.T.A.R. Labs.

Barry awoken from his coma
As they talked about their trip to see S.T.A.R. Labs' particle accelerator that night, Barry helped explain why the particle accelerator was such a big deal, to which she claimed that all he needed was a girlfriend. Joe entered as Barry's DNA sample test finished, and after helping give Joe a lead on his case, Iris requested that Barry be allowed to attend the particle accelerator's switching on, which he was fine with. Once they got there, Barry tried to communicate his feelings toward Iris, though she misinterpreted what he meant as his awkwardness to tell her about his love life. As they began watching Dr. Harrison Wells give a speech, a thief stole Iris' laptop, which had her dissertation on it, so Barry tried to run after it. However, he was winded by the assailant and Iris showed up not long after. They returned back to the station to see Detective Eddie Thawne, whom Iris' dad called "Detective Pretty Boy", with the thief from earlier. She admitted that though he was considerably stuck up, he was indeed pretty.

Following Barry being struck by lightning and put in to a coma, Iris and her father frequently visited him, even when he'd been moved to S.T.A.R. Labs to stabilise his condition.

Nine months later, Iris was working at Jitters when Barry walked in, having woken up. They embraced, she being thrilled to see him, and they headed to Central City Police Department to see Joe. Right as they arrived, Joe and his new partner Eddie Thawne were heading out. Iris greeted him rather coldly, telling him not to keep her father waiting. Promptly after this, Barry stopped a criminal across the room using his super speed, freaking him out. He farewelled Iris and promised to call her later. A while after, Barry met Iris back at Jitters, where he watched on as she kissed Eddie. She noticed him and they went for a walk, where she explained how they'd gotten involved, especially that she hoped he'd keep it a secret. Midway through their conversation, a police car involved in a chase skidded towards them, when Barry grabbed Iris and rolled away. The chase eventually led to a car explosion, which eventually brought police and paramedics. Joe among them, he scolded Iris for chasing danger. When he began yelling at Barry, she tried to intervene, but he refused to stop, causing Barry to walk off. However, they eventually made amends.

A while later, Iris and Eddie went to grab some fro yo, however before they could reach there, they were involved in a car crash. Iris wasn't injured, though as she stepped out of the car, a number of cats from the Central City Zoo began to approach. Eddie attempted to nudge them back with pool toys from a car, to very little success. However, The Flash intervened, zapping them with static electricity, making it appear as if Eddie had done it. Iris admired Eddie as he talked to animal control and they soon left.

Iris went to see Barry at his lab, where she blamed him for her studying journalism, which she described as boring. She reminded Barry of the Simon Stagg event that they were attending together, where he would help her sort through the scientific language, and Barry promised to go home and change as quickly as he could. Eddie walked in and despite acting only slightly friendly towards Iris, Barry reminded them of how he knew about their relationship, and Eddie thanked Barry for keeping their secret. At the event, Barry and Iris walked around with the former explaining to the latter about what it was Stagg was being praised for. After Stagg walked past, Iris attempted to get a comment for her article, though he refused to say a word. Following an encounter with gunman, Barry fainted outside of the building to be found by Iris, when he claimed to be looking for their number plate. Barry and Joe walked off to talk, while Iris talked to Eddie. A while later, Iris queried as to why Joe was mad at Barry. He passed it off a work stuff, though he was confused why she was mad at him. She mentioned his promise to give her scientific background for her article, and how he didn't show. Due to this, she had to find another topic if she didn't want to fail the assignment. He attempted to convey what was going on, albeit in slow motion as he was unable to tell her otherwise. Barry then got called to S.T.A.R. Labs and Iris promised to finish their conversation later. That night at Jitters, Barry apologised for acting distant, though reassured her that he was good at being her friend. Leading from that, he offered to pick a new topic for her article, however she'd already found one. She started explaining how her article was on "the streak" that had saved people around the city, unknowing to her that it was Barry. He called it science fiction, though she decided that it could be an answer to what had really happened on the night of his mother's death.
