Notes

"You shouldn't raise kits with my brother! You and him shouldn't even be mates!" Sootclaw had yowled.
Lionleap didn't even realize he had leaped until he felt blood under his paws. Sootclaw screeched and bit his leg, trying to dislodge the huge tom. But Lionleap gripped harder, feeling a disgusting sense of satisfaction at the younger tom's pain-stricken face.
"What will my brother say when you kill me? Will he still love you? Will the Clan still want you, a half-breed murderer?"
Lionleap's voice didn't feel like his own, more like he was listening to an older cat speak instead of himself. "Would they want a cretin as vile as you, who would rather I die than let me and his brother be happy?" He leaned down to Sootclaw's muzzle, feeling the gray tom's quick breaths on his nose. "You told me you wanted me to leave the Clans forever and constantly harassed me for not having a mother. You spoke with such disdain about kittypets knowing I have a kittypet father. You tried telling my daughters that they shouldn't talk to me or Pebblebright because we aren't good cats."
Sootclaw's eyes widened. "How did you know about that?" he whimpered.
"You think I have no friends in the Clan, do you? I would tell you who told me, but it doesn't matter anymore. You have two choices: leave IceClan or leave me and my family alone." Lionleap bared his teeth. "Which do you choose?"
"I would rather die beneath your claws than live in a Clan that accepts half-blooded cats and toms with toms for mates!" he spat.
Lionleap tried to retort, but Sootclaw powered up and threw him off. With a single strike to his throat, Lionleap was on the ground, panting for breath. He could see and feel the blood pouring from his neck wound, and the light of day started to fade. With the last of his strength, he channeled all of the training he had been given by [Dark Forest mentor] and attacked Sootclaw. The tom was clearly caught off guard enough to be vulnerable, and they both collapsed after the attack.
Voices began to draw near. Lionleap recognized Pebblebright's, as well as Whitepelt and Cliffstep. He tried to make out the fourth cat present, but his vision had faded so much that blurred pelts were all he could see. The last thing he saw before the darkness consumed his vision was Pebblebright sobbing.

Cliffstep stared down at the two toms. Blood poured from huge wounds in both of their necks and their chests barely moved. "What are you waiting for?" Whitepelt hissed. "Pebblebright, help them!"
All four cats' pelts were standing on end at the sight. It was a bloodbath. His son-- his /adoptive/ son, was losing blood fast, and he had no training to help. "Blueflower!" he hissed. "Get cobwebs. Quickly."
Blueflower raced off. Pebblebright collapsed between the two dying warriors, clearly unable to choose who to grieve for first. One his brother, one his mate, both about to join their ancestors in StarClan.
Blueflower returned with a bundle of cobwebs which he hastily shoved under Pebblebright's nose. As the tom began to work, Cliffstep sat down with a thump. He had practically raised Lionleap, yet he could tell by the fur between his teeth and claws that he had been Sootclaw's attacker. Sootclaw clearly fought back, though, by the bright golden fur in his claws. "They attacked each other, and now neither of them will survive."
"That's not true," choked out Blueflower. "Pebblebright will save both of them. Lionleap won't die."
Cliffstep rested his tail on the yellow tom's back. "StarClan will ultimately decide. We just have to hope they grant mercy on those two."
