in season 5 we have seen some scenes that make teresa a suspect more than in previous seasons..we have to realize that the main characters of the mentalist are teresa and patrick.therefore it makes sense that in the series finale there has to be some kind of a showdown between these 2..in season 5 teresa has been shown to be macabred to say the least.twice we have seen dogs bark at her....the evil look...it wouln't susprise me to see her in the final 7 suspects list...from the beginning i've been saying that teresa and patrick relationship looks more like brother and sister than a romantic relationship.and we don't know who the third brother is...i have also said before that i think vanpelt could be revealed as a relative of red john if teresa isn't revealed to be rj we know from prevoius episodes that teresa was raised in chicago and patrick,danny and alex have a past history in chicago.so there's a conection between teresa and patrick...don't know the motive yet though.angela's granparents used to own many companies troughout the midwest working with steel...roy tagliaferro...cut iron...iron..steel....so rj,pj and lisbon and angela are somehow connected...also remember how patrick is the opposite and has a way with animals. these people have been mys red john suspects for a long time...jane,lisbon and van pelt..it could be that they are not rj perse but the mastermind behind it.
