I can't believe Thomas Mcallister is red john I refuse to for many reasons.
1. so many questions were left unanswered and they barely had gone any where yet with this tiger tiger organisation it had so much potential.
2. The red john we see in earlier seasons is totally different to how Thomas Mcallister is.
I'm not saying he isn't Red John but in my mind he isn't I will never believe he is even if the series end with no other red john, it wasn't even a let down because I expected so much it was a let down because it had no emotion in it compared to the fake red john ending we saw in season 3 and compared to the first time we hear red johns voice
