I kind of understand Abbies distrust in Ichabod, and she had a legitimate reason because he did draw the map again. But the real manipulator here was Parrish/Jeremy. Im not sure things would have played out the same if he hadn't planted those seeds of doubt, aka fear of betrayal in Abbie.
I was one who liked the finale, but I too am worried that next season has the possibility to turn into the Ickatrina show. Now that shes out of purgatory no doubt she will be featured more, which means more time with Ichabod and less I/A. I hope we are wrong, but I am hoping at the very least for some delicious angsty tension between Ichabbie next season after their reunion of the century of course.
