I don't remember that, or even a "To Be Continued". All I remember, was Nick saying "Mom?", then it was over. Must have been different on the DVD than on the NBC broadcast.
I would agree with others, that the whole Adalind storyline causes the show to come to a screeching halt. With her being upgraded to regular cast member, I guess that means she will be sticking around for a while. And won't see Claire Coffee dealing with Zach Morris in the upcoming season of "Franklin & Bash", where she is actually a lot more tolerable.
Where did you read that at?
