She wanted to see me hunt Kyurem, she was like "Let's go hunt that Shiny!". So Encouraging. Sadly Kyurem wasn't there... Does anyone know how to fight Kyurem? I've beaten the game. Thought that was all I needed to do...

I assume this is B2/W2.
You need to visit N first, in the ruins of Team Plasma's castle. Remember when your rival's sister said something about Zoroark in Victory Road?
Eventually you'll have to battle N's Resh/Zek (depending on your version), and after that, capture the Resh/Zek in Dragonspiral Tower. Only after that you can go capture Kyurem.
It is actually mentioned on this page ;)
