That's what you choose to quote out of everything I said?
Faust, read what I posted again. Light still had Death Note paper in his watch/wrist thing, so it's not as if he couldn't kill EVEN when he had the others. Misa and the Yotsuba Group guy are with L, but Kiyoma and Mikami Teru were when Near was around.
The Mentor hasn't been cornered by anyone, so it's not as if he couldn't kill on his own here. I actually thought that the role should gain the Detective-resistance of the Mafia Boss, be able to kill on his own, and recruit a Sith Apprentice, who could then choose to kill. The one benefit of the Sith Apprentice is that they're sort of forced to follow your orders, whereas a mafia member can choose to play however they want.
