This storyline is weak.
First: Jennifer and Jack left Salem after one meeting. Never would that happen. They would stick around and try and work with her to regain her memories, they would look for inconsistencies, they would want to believe. Not skip town and live their lives like this didn't happen. Reality is Days probably didn't have the budget for them to stay long term, so in my opinion, don't write the storyline.
Second: Does anyone really think that Julie would stay out of this? Never, ever would that happen. She would call her out after her first interrogation of new Abby. I realize that Susan Seaforth Hayes (Julie) is probably off camera during this time because of her personal life, but in Salem world this would never happen.
