In some ways, Riza would always know she was Roy's queen, and that it was why they would never be together. A king never sacrificed his queen by revealing her purpose. That's why it never bothered her when he would flirt and tryst with the multitude of women he did- they meant nothing to him, not when it really mattered. At the end of it all, when judgement was called down on him, it would be her standing beside him. Riza Hawkeye would be with him until the very end and none of his women could say that. In truth, if not in fact, they were married. He was her king, her commander, and her would always be Riza's everything.
Martel would always be Greed's loyal second, and she could see the same in the other blonde woman. So different, and so very alike, they were the queen pieces of their respective superiors' chessboards. It still made her jealous and angry to see the homunculus dally with other men and women, but that was just who he was. He acted out of his sin, and a desire to be as human as they were, a desire that contrasted sharply with his plans for domination and immortality. She couldn't fight it, though. When you lived with Greed, you got used to such things. Besides, he was the Boss. He'd always be the Boss, no matter what lay unspoken between them.
Tears had not graced Hawkeye's face in years, but today she wept openly. All that they had sacrificed, only to see Roy fall to some heartless homunculus. It was too much for her. She screamed out her rage and grief at the creature that called itself Lust, the same creature that had seduced and murdered Havoc. All of her pain, her guilt at her unfinished work showed on her face. When her gun was empty and her tears were done, Riza fell to Lust. Perhaps it was the homunculus that killed her, but more likely it was the weight of her broken promise. "I have someone to care for," she whispered, her words breaking the silence. The cloying scent of blood and death hung heavy in the air above her. In the end, Roy's queen failed him.
Martel did not weep. She did not cry, and she did not scream, only lay in the puddle of blood that wasn't entirely hers and broke. Dorchette was dead, and so was Roa, -they lay only a few feet away from her- but that wasn't the worst of it. Greed was gone, stolen from those who loved him. She'd still been conscious when that wretched bastard murdered him in front of them. There was no kindness from the Fuhrer's government for them, not even in death, she realized. Even after they'd been tortured, set up, and experimented on, there was yet more pain in store for them. She resigned herself to her fate. It was her own fault, of course. She had not done what she was employed to do: protect Greed. He'd warned her that his family would come for him, and she had not listened out of pride. There had just been so many times it had seemed like he was dead for good and come back for her to believe he could really die. Now he was dead, and she lay dying beside him. For the first time in her life, Martel gave up. As her last breath was fading away, she muttered, "Long live the king."
