Can you name a time other than Sora that the keyblade chose someone who'd didn't gone through the ceremony? Sorry but our point still stands. Sora's the only exception to that rule cause of his connection to Ven and Riku. Yeah the keyblade chooses its master but it doesn't chose any random fluzy.1. The Keyblade chooses its Master
2. Maybe it's a chance of redemption for Lea. He done alot as Axel and only had a chance to change because of Xion and Roxas. THink of that.
But dose he need a keyblade to do so? On of the likeable things about Axel/Lea was how he wielded his Chakrams with such awesomeness against powerful foes and now that uniqueness is gone. :/
