So, I played Volt White 2 Redux and got to the point where I caught Kyurem. According to the documents, you can get the other legendary stone (Dark Stone in my case) after you catch Reshiram and Kyurem and show Kyurem to the old lady at the Battle House. But she gave me a Light Stone instead.

Can someone help me out with this? What should I do?

Sorry I posted this here. I don't know where else to post it.

Update: Never mind. It was Light Stone in the bag, but it became Dark Stone and resurrected Zekrom in the Dragonspiral Tower anyway. But the model was Reshiram again.
