Bluestar refused to make Swiftpaw a warrior due to her paranoia and mistrust in her Clan, and she only trusted Fireheart and his apprentice Cloudpaw, who did not believe in StarClan. When only Cloudtail was named a warrior, Swiftpaw, motivated by his anger and a need to prove his worth, and Brightpaw devised a plan to discover what creature was stealing their prey at Snakerocks. He hoped their bravery would convince Bluestar to name them warriors, but it resulted in his death and Brightpaw's grave injury.
