.The.Flame.

Mousewhisker emerged from the emerald green bushes and approached the creek. He sat down beside it and looked into the water, pretending Hollyleaf was sitting besides him. Hollyleaf had been the first she-cat to love him. Most cats hated him, because he was technically a kittypet, since his mother and father were both barn cats. Most ThunderClan cats couldn't see past this fact...but Hollyleaf did. She saw his inner warrior. She loved him for who he was, not where he came from or who raised him.
He looked up at the sky and pretended Hollyleaf was sitting right besides him, purring her sweet, innocent purr. He loved her more than words could describe. He had gone crazy ever since the news of his love's death had reached his ears and he recalled yelling at Hazeltail, his own sister, when she practically did nothing wrong, just gave him a vole when he asked for a mouse.
"Oh, my dear Hollyleaf," he whispered, tears dripping from his whiskers. "You were the first, you'll be the last. I swear to StarClan, I will never love another she-cat."
He remembered Minnowpaw. He hadn't seen her in such  a long time....and even though he was attracted to her at one point, she never loved him. She thought of him as a friend and a friend only. That's all he would ever be to her. Plus, she was a RiverClan cat. RiverClan cats were forbidden to love ThunderClan cats, of course. It had always been against the rules. Him and Hollyleaf were perfect for each other...but Hollyleaf was dead.
He felt tears streaming down his gray-patched face. He remember how traumatized she had been by the fact that Leafpool and Crowfeather were her real parents and that she had been living a lie her whole life.... traumatized enough to announce the treacherous secret at the Clan gathering, in front of all the Clans. He also remembered the little secret she had told him: she had killed Ashfur, to prevent this from happening. Then, she did it herself....
Mousewhisker knew his beloved had went a bit insane...but he understood.
"I understand, darling," he soothed, pretending it was Hollyleaf he was speaking to instead of himself. "I understand."
She had told this secret to only him, not even to her brothers, Jayfeather and Lionblaze. They had brought the news of her death to Mousewhisker and the rest of the Clan.
She had been chasing a squirrel and the squirrel had ran into the tunnels that divided WindClan and ThunderClan, two Clans that had been battling often. She'd ran into the tunnels, but they had collapsed on her. She was crushed by rocks and unable to get out. He tried to imagine his beloved: struggling beneath the weight of many rocks, all of her strength gone, bleeding onto the cold stones, no breath left, closing her eyes for the last time in her terribly short life...
Mousewhisker yowled and finally knew he'd had enough of mourning.
"Hollyleaf!" he yelled to the stars. "I hope you hear me, because I want you to know that you're the best thing that has ever happened to me! I love you and I always will! In your time of darkness, I will be the flame!"
With that, with a heavy heart, he padded back to camp. Little did he know, above him, in StarClan, a black cat was looking down at him.
"Oh, Mousewhisker," the black cat whispered. "I love you, to."
