Birth by Sleep Riku's and Kairi's Keyblade. **Spoilers**

We all know the famous scene in KH2 where Riku gives Kairi a flowery Keyblade that she wields in one short scene.
Nomura has hinted that it's Riku's Keyblade and he Dual Wields and lent it to Kairi.
I read that in BBS, Kairi gives Aqua flowers when they meet and it unlocks the same keyblade, called Destiny Place, for Aqua.
Not sure if this is true, but if it is, how does Riku get this exact blade?

Is it possible that when

Spoiler

Aqua gave Terranort her armor and Keyblade to save him at the end of BBS, he also got all her Keyblades and when his Heartless possessed Riku, which could be how Riku dual wields, Riku was able to access that Keyblade?

 

There's kind of a lot of Ifs in there... and I'm not sure that Nomura hinted that but it's certainly a possibility!

 

when did he hint that Riku duel wielded?

 

He didn't really hint that but he said something to the affect that the Keyblade was made from his memories of Destiny Islands which implies that it was HIS keyblade that he lent to Kairi and he held it at the same time he'd been wielding Way To Dawn so... it is possible that Riku can duel wield.

 

That is the keyblade Kairi used.
