Quote adoakey23: Phyllis and Nick noooooooooo way. But Sharon has put Nick through way to much, men in the past and then Brad, Nick forgave her, he does one thing wrong and now Sharon feels so sorry for herself. I think it will turn out that the baby really is Jack's. And Nick will be let down again.
Nick has done more than one thing wrong - he slept with Grace to begin with and she was Sharon's best friend at the time! What a betrayal by both of them. After Cassie died Nick was totally unsupportive of her - any time she needed a shoulder to cry on or needed some moral support he just ignored her.
