Actually... Fireheart/Firestar never "LIKED" Bluestar. But he did deeply care for her and respected her as great trustworthy friends, Bluestar in the other hand sees Fireheart/Firestar as her son or trustworthy friend. Nothing more than that.
Bluestar's deputies before Fireheart were Redtail and Lionheart. Redtail served as deputy before his death in a battle against ShadowClan, and Lionheart temporarily took over until Fireheart was appointed.
After Bluestar dies, she is succeeded by Firestar (Fireheart) as leader.
Fireheart becomes deputy of ThunderClan when the former deputy, Redtail, is killed in battle. Bluestar appoints Fireheart as the new deputy due to his loyalty, courage, and strong leadership skills, despite some initial reservations about his past as a kittypet.
Firepaw becomes fireheart in into the wild and later in the darkest hour he receives his leader name firestar (after Bluestar dies).
No. He tried to in Forest of Secrets, but Fireheart(Firestar) stopped him. Bluestar gave up her last life by attacking the lead-dog who was about to kill Fireheart and knocking him, and herself over the side of the gorge. Fireheart jumped in and tried to save her, Mistyfoot and Stonefur helped, and when on dry land again Mistyfoot and Stonefur forgave Bluestar for giving them away. Bluestar told Fireheart about the prophecy 'fire will save our Clan' and said. "Fireheart, you are the fire that will save ThunderClan" Then she died and went to StarClan.
I am not overly sure but what I know is that Fireheart saved Bluestar as Tigerclaw stuck his teeth to her neck. Tigerclaw retreated followed by shadowclan outlaws but Bluestar survived, and Fireheart was promoted to deputy.
after she dies, fireheart becomes firestar, and graystripe is made deputy.
Bluestar losses her last life at the end of the 5 book (A Dangerous Path) in the first series.
Yes, she does. Bluestar dies in the end of the fifth book of the original series because of a pack of German Shepherd dogs pull her into the river with them and then Fireheart pulls her out to safety but she knows she's already on her way to Starclan. And then she dies, leaving Fireheart to become Firestar, leader of Thunderclan. And if you want to learn what her life was like the moment she opened her eyes for the first time to the moment she dies, check out the Warriors Super Edition "Bluestar's Prophecy".
Warriors: The Darkest Hour
Fireheart was a trustworthy cat because he showed the qualities of a good warrior. He was brave, honest, and not afraid to speak his heart. These were the things that got Bluestar's attention on his first day in the clan.
No she dies in the second to last book of the first series. She died saving Fireheart.
