She has been kept from completing the mission she was assigned upon her arrival in Salem, but now, a new threat will force Serena (Melissa Archer) to go through with finishing her task on Days of Our Lives.

Serena's Secrets Revealed

Her unknown, unseen accomplice has become increasingly desperate for her to finally snatch Eric's (Greg Vaughan) elephant statue and replace it with the one she has. And while Serena has gotten close in the past to doing what she was dispatched for, her efforts were thwarted when she tripped in his apartment and was seen by Nicole (Arianne Zucker). After lying that the thing she was hiding was a present for Eric, she was unable to finish the task.

Now though, her accomplice will up the ante against her, giving her more reasons to try and complete things quickly. Her accomplice will threaten Eric's life in an attempt to get Serena to complete things quicker-and though she may not genuinely want to rekindle her romance with Eric, she does still care about him and doesn't want him to get hurt-and she will be spurned into even greater action to try and switch the statues.

Paul Realizes His Horrible Mistake

Meanwhile, the reverberations are still being felt around Salem from the truth about Paul (Christopher Sean) and Will's (Guy Wilson) affair. Sonny (Freddie Smith) remembered the truth after Paul paid him a visit in his hospital room, and ordered his ex-boyfriend out of his life-and is currently planning how to confront his husband about his infidelity.

Now, a disheartened Paul has realized what he did (he was unaware Will was Sonny's husband), and will seek out Marlena (Deidre Hall) for guidance-though the confession will rock her as well because she is Will's grandmother.

Days of Our Lives airs Monday-Friday at 1 p.m. on NBC.
