Goodbye Arianne Zucker!

As many "DOOL [VIDEO]" fans already know, actress Arianne Zucker will be leaving the NBC soap opera in the very near future, and this could be the storyline that sends her out of Salem for good. Nicole could head to jail for the murder of Deimos, or she may decide to skip town again. However, it seems more likely that "Days Of Our Lives" will send her off, with her daughter Holly in tow, to live in a new city (hopefully) happily ever after, until she may return to Salem again in the future.
