Of all the secondary characters in LOST, Helen Norwood would probably be nominated as the most important to the underlying mythology themes of the series. She was a saint compared to all the sinners.
Helen was Locke's girlfriend for a period during his life before the plane crash, whom he had intended to marry. (In the sideways world, they were engaged to be married in October, 2004) After Locke returned to the mainland in an attempt to bring back the O6 survivors, it was revealed that she had died of a brain aneurysm in 2006.
Locke's relationship with Helen was a bitter triumph of self-destruction. Helen had the patience of a saint. She kept giving Locke chance after chance, but Locke refused to let go of his past. Locke's anger, frustration and revenge for how he perceived his life going so wrong clouded his judgment that the best thing about his life was right in front of him: Helen, who unconditionally loved him before and after his horrible disability.
Locke and Helen met at an anger-management support group of which they were both members. After his outburst at the group about their whining, Helen approached Locke outside and told him that she appreciated his candor and shared his frustrations. She also flirted by telling him that she liked bald men - despite Locke not being bald she said that she was prepared to wait.
Their friendship moved to the bedroom fairly quickly and continued to blossom. During a meal at a restaurant, Helen gave Locke a key to her flat as a six-month anniversary present. She told him that she'd followed him and discovered that he was sneaking out at night to lurk outside his father's house. The gift of the key was given on the condition that he stopped going there, to which Locke agreed.
Despite his promise to stop, Locke continued to spend long periods in his car waiting outside Cooper's house. Helen followed him again and shunted her car into the back of his, stormed over to his window and snatched his keys from the ignition. She threw the keys over the security gates in the drive and implored him to give up on his obsession and take a "leap of faith" with her. Shortly after, Locke moved in with Helen. Locke eventually started making plans to propose to Helen over a romantic picnic. Unfortunately on the morning of the picnic Helen spotted Cooper's obituary in the newspaper and that the funeral was scheduled for that day. Helen accompanied Locke to the funeral to support him. Some days after the funeral, Cooper revealed to Locke that he was still alive and convinced him to participate in a criminal financial scheme in exchange for a share of the money. Locke's suspicious behavior and a run in with gang members searching for Cooper led Helen to follow him again. She turned up at the motel, where Locke was meeting Cooper to hand over the money. She demanded of Cooper: "Are you him?", slapped him and berated him for his treatment of Locke before leaving to go back to her car. Locke caught up with her in the parking lot outside and pleaded for forgiveness, went down on one knee and proposed. Helen shook her head and drove off.
But Helen was with Locke in the sideways afterlife. Things seemed different. Cooper was in a nursing home, unable to speak or function, but Helen took care of him as well as Locke. She was not demanding but supportive. Helen was the embodiment of a good partner: kind, charming, witty, loyal, trusting, helpful, and nonjudgmental.
Helen was the best thing in Locke's life, but he failed to realize it. In all relationships, there are fleeting moments where a couple becomes a couple, connects as a couple, and lasts as a couple. There are few if any second chances at romance with a person spurned during a first encounter. Locke had several chances to make things right but he failed over and over.
Helen deserved better. Much better. She was like a guardian angel who gave Locke a glimpse of what he life "could have been" if not for Locke's delusional self-torment issues.
Helen also deserved a better ending in the series. We are told she died after breaking up with Locke. She died alone. She did not meet Locke in the sideways church to share or rekindle their affection for eternity. So, despite doing nothing wrong, Helen's soul is apparently trapped in a purgatory of Locke's own creation. That's a sad fate for a character who did nothing wrong to deserve such treatment.
It is almost a reverse life lesson. Locke, whose bad behavior and choices, hurt so many other lives but he was rewarded with eternal life with his island friends. Meanwhile, Helen, who took care of people, was kind and loyal to a fault, gets nothing for being of high moral character.
