I chose "someone else" because the dropdown's choices were all single individuals. I'm skeptical that it's as simple as Red John being one of Jane's final 7 suspects. Yet Bruno Heller said, "You can trust the list." What's the trick or catch? Well, how about if Red John is two people ... one who does the killings, the other who's the mastermind? Anyone on the list is capable of being the killer, so in that sense, we can trust the list. But is the mastermind also on the list? Maybe, maybe not. Personality-wise, who's the only person with the charisma and intelligence to match wits with Jane. Only Brett Stiles. But remember Jane said Stiles couldn't hurt a fly. Not personally. So he had someone do his bidding? Or maybe it's someone like Walter Mashburn, who's not on the list and arrogant enough. So who's methodical enough and cold hearted enough to be the killer? It would have to be a someone good at keeping secrets, as well as someone smart. And someone on the list. I like Kirkland for that. The others have some screw loose that would make them risks for Red John to trust. We already know Kirkland killed for Red John. Anyway, that's one way to "trust the list" and still have a twist, even someone not on the list.
