Because their mother and father (Sandstorm and Firestar) never had any other mates besides each other.
YES. in one of the books, Ashfur tries to kill the Three but Squirrelflight says that they aren't really her kits. Later, the Three unravel the web of mysteries and find out who their true parents are.
Leafpool gave her kits to Squirrelflight because she thought she was doing the right thing. Medicine cats can't have kits so if she used Squirrelflight she could contiue to be a medicine cat and her kits wouldn't grow up being half-clan and looked down upon.
Because Leafpool is suspicous of Hawkfrost and Brambleclaw is spending a LOT of time with Hawkfrost and, of course!, Squirrelflight sides with her sister, and Brambleclaw won't refrain from seeing his half-bro.
His two daughters are Squirrelflight and leafpool (daughters of firestar and sandstorm). Firestar does not have a half-son but he has a half-brother who is scourge (because they have th same father jake).
Firestar's daughter is Leafpool and his half-son is Brambleclaw. Leafpool is a medicine cat in ThunderClan and Brambleclaw becomes the leader of ThunderClan, taking the name Bramblestar. Both cats play significant roles throughout the series.
Ok so in books one to five (and a half) of Power of Three you should believe that Squirrelflight and Brambleclaw are Jayfeather, Hollyleaf and Lionblazes parents, except for little snippits here and there, if you read carefully. But when Squirrelflight gives out the secret, you should know exactly who their real parents are, if you refer to book five of The New Prophecy: Twilight.*Spoilers Alert! Spoilers Alert!*Ok you know how Leafpool and Crowfeather ran away from the clans, and if you go on Warriorcats.com you can read a play called after sunset, when Leafpool tries to tell Crowfeather something? And at the end, Leafpool says something like: "Goodbye, Crowfeather. I hope we don't regret not meeting here today." Oh yeah, and when Brambleclaw was deputy, and he thinks, "even slender Leafpool is looking plump." PLUMP WTH KITS! So that's like the biggest hint of all times that Jayfeather, Lionblaze and Hollyleaf are Leafpool and Crowfeather's kits.
Their kits where believed to be jaykit/paw/feather hollykit/paw/leaf and lionkit/paw/blaze, but they are really leafpool and crowfeathers kits. Squirrelflight lied and told the clan that they where her kits and not leafpools because the kits were half clan and leafpool was a medicine cat. But hollyleaf died when the tunnels collapsed while she was trying to run away from her clan to start a new life. Squirrelflight tells Ashfur that hollleaf,jayfeather,and lionblaze are not her kits because Ashfur was going to let them burn in a forest fire because he once loved Squirrelflight but she chose Brambleclaw over him so he said to her letting her kits die would hurt her in away.Then Squirrelflight tells Ashfur that they are not her kits and he wont hurt her by killing them. Later you find out that jayfeather and lionblaze are really Leafpools and Crowfeather of Wind Clan kits. Squirrelflight and Leafpool lied to protect Leafpools kits and Squirrelflight told everone that they where Squirrelflights and Brambleclaws kits. In Sunrise Leafpool resigns as medicine cat leaving jayfeather as a full medicine cat and Leafpool as a warrior.

dont think so. Uncial = Uncle..? If so, then yes, I think. They were half brothers. Since Leafpool is his daughter, I guess that makes Scourge the half uncle~?
Ivypaw or Tigerheart is one of the rumors going around. Personly, those choices don't make sense. So, I'm going to tell you MY opinion ( Heh Heh!). I think the fourth is Squirrelflight. Dont believe it? Here is some proof ( kinda ) 1. When Jayfeather found out there was a fourth, Half Moon said " SHE's closer than you think. And Squirrelflight was in the mountains with Jayfeather! 2. The cat on the next cover isn't Hollyleaf ( I know i lot of you were hoping for that! ) It looks a lot like Squirrelflight. And below the main picture, there is a cat chasing a SQUIRREL! 3. Squirreflight has powers! She can sense the feelings of Leafpool. Those are my reasons. I know you probably will still think its gonna be Tigerheart or Ivypool, but it doesn't make sense. Tigerheart doesn't even have anything to do with the prophecy, and he's not from Thunderclan! I'm another person, I think the fourth prophecied is Leafpool. mainly because how he said Squirrelflight can sense the feelings of Leafpool, so can Leafpool. Leafpool can sense the feelings of Squirrelflight. Also, the cat chsing the squirrel is Leafpool, I know because if you go to warriors.wikia.com and type the forgotten warrior it says the cat chasing the squirrel on he cover is Leafpool. Another person- Leafpool does make sense. It could also be Hollyleaf because the closer than you think thing. She was closer than he thought and could be the forth cat. Another person- I read online that it was breezepelt, but that doesn't make sense because he tried to kill jayfeather. i also know it is not hollyleaf. Yet Another Person - I think it's Cinderheart. StarClan had to have a good reason to bring her back, right? it only names sense. Plus, It can't be Hollyleaf because she isn't in any more prophecies. The whole Leafpool/Squirelflight thinng would he logical if there was 5, but not 4. Plus, I can sense how my friends are feeling baecause I know them. That's why they can tell. As for Breezepelt, no. He's a Dark Forest warrior.
Brambleclaw does not hate Squirrelflight. While they do face their share of challenges and misunderstandings throughout the "Warriors" series, their relationship evolves into one of love, trust, and partnership. They ultimately remain loyal to each other and their Clan.
