Yeah I never thought that he thought Locke wasn't Locke.

I thought Ben told Richard that Locke wanted to kill Jacob but I can't remember for sure, all I remember is Ben telling Locke that he didn't tell Richard. Obviously Ben lies but he was supposedly following John then.

I know Ben and Richard talked about Locke and how he might be dangerous or something but I don't remember if Ben told Richard that Locke wanted to kill Jacob.

Anyway, just speculation.

So much cliffhanger stuff this finale.
