Im  most dissapointed by the fact that in the end, Jane was clueless and really though that Bertram was RJ... I mean, Jane has always been smart and seemed to have it all together. But when he encountered Bertram in the church, he rally thought he was RJ, and when Bertram responded that he in fact wasn't, Jane was clueless. 

So insanely bad writing that it makes me want to sue Heller for the years and hours of my life that i've now wasted.
