Only one way to save this soap opera now:

It was clear to the FBI (as well as to all of us) that Mcallister couldn't be red john

They knew it had to be Jane (multiple reasons have been listed 1000 times)

That's why they bring him back to the country with the excuse the FBI desperately needs him (who would buy that anyway.. it's the freaking FBI)

They've been trying to push him so he would crack / make a wrong move all along (probably his moves followed by someone from the FBI, Lisbon not likely in on this - higher up)

That'd be why Abbott doesn't really care about the BA list

Pike going after Lisbon / potentially taking her away could be a first attempt at this

The death of a team member would be another attempt for him to crack

Clearly another psychic who wants to stop a serial killer and goes on tv to stop him is over the top so Jane finally kills the guy - and writes 'fake'

The wedding could go ahead and they could catch him or not - but maybe we will see jane drawing a red smiley face in one of the last scenes

Bruno saying that Jane is not red john wouldn't be a big deal since those would be 2 split personalities of a disordered guy (none of them are real) - so technically Jane (personality) would not be red john

This is the only way seasons 6 and 7 would make any sense - as a plot to catch Jane - hopefully they'll get it right - answer tomorrow..
