Not only Abby, but Ilias Webb is listed in the Role of Kevin, who was also in the credits for Breaking Glass. Kevin was the boy that was teasing Emma and messing with the Video Camera in the video clip seen at the end of Breaking Glass.

So my speculation is that there will be at least one flashback to the time when Emma and Ingrid were together in the Foster System.
