However, it looks like they also share a few close moments while going through old memories in the DiMera living room. Chad has been doing anything possible to get "Abby" to remember, not realizing it's a fruitless endeavor because the woman is an imposter.

Neither one of them is aware that Steve's nagging suspicions lead him to ask Kayla to perform another DNA test on this mystery woman. However, they will have to do it on the down-low to make sure nobody can tamper with it. After all, this is Salem, so tampering with DNA tests seems par for the course.

Sarah's memories

After her hypnosis session with Marlena, Sarah is sure she didn't see Brady driving the car that hit her that fateful night. However, she still can't make out the face of the person behind the wheel.

Sarah remains confused and frustrated. On Monday, Sarah and Maggie commiserate over the failed attempt to remember what happened the night Sarah was hit. Will Maggie encourage Sarah to try more hypnosis?

While Fiona is relieved Sarah still can't identify her as the driver, the guilt is becoming too much. When she prepares to make a confession to Xander, is she ready to tell him that she is the one who ran down his new wife and set up Brady to take the fall?

Fiona has been determined to repair her relationship with her son, but this one bad move might cause Xander to never speak to her again.

Alex and Stephanie grow closer

Stephanie is still recovering from losing Everett and from the hurt that came with being one of only two people to attend a memorial and scatter Everett's ashes. However, she is happy to have a friendly neighbor across the hall who gives her a shoulder to lean on.

Alex and Stephanie could be picking up where they left off now that they are both single and in close proximity again. Could they get things right this time?
