"Ack!" Ventus scoots back as Void Gear impales itself into the wall, knocking over some VERY NICE pottery, calling his own keyblade to his hand without a second thought and spinning it. Unlike some idiots--his amnesia had not effected his overall combat capabilities, and he begins calling an aero spell. He leans out the window and aims, fires at Vanitas's vantage point. See if that won't knock this rude stranger down a few pegs. Ventus liked that pot!

And well, Xehanort might have liked it to. Ventus really didn't want to think about how pissed he would be.

"Why would I tell you that!" He shouts up, waving his keyblade angrily with his little baby arms. "It's not my problem if you're to stupid to plan an assassination properly! Get out of here! I'm busy! Master Xehanort will be back later if you wanna die!"
