My thoughts on this: I voted no and no. But I only voted 'no for Abby' because I want to see the drama that happens. Abby has, many times, been this holier-than-thou bore who barely paid for what she did to Austin (and Carrie, for that matter). The truth should be exposed, but I doubt her reputation will go down the drain all that much. When Salem has the punching bags in Theresa and Nicole, as well as Eve, and Sami the perpetual lazy-susan-loins, I don't think many people will be all that upset about what Abby did for long-especially since nobody really thought Sami and EJ were meant to be together. But I'm all for making EJ pay for good.
Now, as for the topic of whether she will forgive EJ or not, I doubt she will. Why would she? She brought up in the 7/10/14 episode that there is nothing to milk from her relationship with EJ. He made a fool out of her for the umpteenth time, and I think she now realizes he hasn't changed and never will. As for the fans, I think most EJ-Sami fans were finding themselves bored with this pairing around the time EJ first slept with Abby. They did nothing but fight, and many fans complained that Sami made too many messes for EJ and was ungrateful when he cleaned them up. That, coupled with the fact that many now view the couple as tarnished from the affair and Sami's revenge, means that there are few people who are rooting for them to make it out of this. Plus, loads of Sami-EJ fans began to prefer him with Abigail after their romps and chemistry aired.
