I think what they decided on is that Lancelot is going to actually be at the door while Kariya is inside. It's a fake out Boss team up! You think you've won if you manage to get passed one and then, bang there's the other! LOL!

Lancelot is also talking about maybe leading people away using his shapeshifting ability. I hope this happens at least once with someone. It would be very amusing to watch!
