What if Tigerclaw Succeeding in Killing Bluestar? This takes place when Tigerclaw brings his rogues into the Thunderclan camp and is in Bluestar's den trying to kill her during the battle.
Fireheart ran in the den, pawsteps too late. Tigerclaw had Bluestar pinned down, and had his paw in the air. "I'll rule the forest. I'll show Thunderclan I am a much better leader than you could ever be!" Tigerclaw hissed. "Bluestar!" Fireheart yowled as he crashed into Tigerclaw. He never expected it, so he came down easily, but Tigerclaw wasn't stunned for long. He bounced to his feet and threw Fireheart to the wall, then leaped on Bluestar. Fireheart hopped to his feet and onto Tigerclaw's back, trying desperately to pull him off of his beloved leader, but before Fireheart could pull him back, Tigerclaw leaned forward and bit down on Bluestar's neck. Fireheart ran to her side. "Bluestar, Tigerclaw's wrong. You are the best leader Thunderclan could ever have. Don't leave. Please," Fireheart told her. She looked up at him, her chest moving up and down slowly. She was alive, and might live if he could get her saved. But Tigerclaw bit onto the back of Fireheart's neck and tossed him to the wall. Firestar instantly tensed his muscles and leaped onto the dark tabby warrior and bit and scratched him. Tigerclaw raised his massive paw and swiped it across Bluestar. "Fire will save our Clan. Firestar, you will save Thunderclan. Take care of the Thunderclan cats," bluestar meowed hoarsely. Then her eyes glazed over as she looked at something past Fireheart's shoulder. Fireheart couldn't move. Then rage surged through him and he pounced onto Tigerclaw. He rolled into the clearing, and then Tigerclaw tensed his muscles and threw Fireheart off him. Then he ran to the rogue cats and battled them off. But something was odd about the way he fought, and Fireheart saw his claws were sheathed. "Did you see that, cats of Thunderclan? Fireheart attacked me, he is a traitor!" Tigerclaw said. "No I'm not!" Fireheart protested. "I just saw Tigerclaw kill Bluestar! He led the rogues here, and then snuck into her den to kill her and become leader!" "Fireheart, I tried to help Bluestar. she was injured in a battle with a rogue, and I tried to help her, but you wouldn't let me, and she died,"Tigerclaw said with symphathy in his voice. Fireheart ran to Bluestar's den and pulled out Bluestar's lifeless body. "Look at the claw marks, cats of Thunderclan! My claws aren't nearly that big, and I saw Tigerclaw in their right now kill her! The marks match the size of his claws perfectly. And you saw him roll out of her den!" Fireheart said, hiding how desperate he was for the Clan to believe him. "If his leader was killed by rogues, then why did Tigerclaw fight the rogues right now with his claws in? And I saw him a few days ago talking with Brokentail, sharing tongues with him, though he calls him a traitor! What do you have to say, Tigerclaw?" Tigerclaw snorted. "I say you're banished from Thunderclan. You tried to make my Clan turn against me, when they all know I will be a great leader. Leave, Firestar," Tigerclaw snarled. Fireheart walked out of the Thunderclan camp. He was not alone though. As he passed by, Cinderpelt, Yellowfang, Whitestorm, and over half of Thunderclan followed Fireheart. Together, they would get their Clan back, and Firestar would be leader of it all.
We all have our moments: A moment to cry, a moment to laugh. A moment to be held, a moment to be let go. A moment to be sad for not having what we want, and a moment to be happy with what we got.
Yeah, we all have those moments. And I advise you not to put them to waste.
