They had appeared to put their difference aside for a while, but things are set to heat up on Days of Our Lives once again, as Sami (Alison Sweeney) and Kate (Lauren Koslow) once again reignite their intense rivalry.

Marlena Blasts Sami and Kate?

Sami is nearly ready to walk down the aisle with E.J. (James Scott) and officially become Mrs. DiMera once again -- and for the last time. Though E.J. has kept some pretty big relationship-threatening secrets from her (including an affair), the couple is ready to take their vows. But Kate will now see to it that it doesn't happen, because she has reunited with Stefano (Joseph Mascolo) and can persuade him to ruin things for the couple.

In a preview clip for the Friday, June 13 episode, she will even snarl to Sami that only one woman with the name DiMera can live in the family mansion.

Sami and Kate Implicated When Gabi Makes A Second Confession?

"There can only be one Mrs. DiMera in the mansion...and it won't be you," she says to Sami.

With those words, and her plans to marry Stefano again and officially stand in the younger couple's way, one of Salem's most intense rivalries will officially be back on, as both couples will potentially race to be married first, in the hopes it will thwart the other's plans.

Meanwhile, Sami's son, Will (Guy Wilson) has already gone through a lot in recent weeks. He nearly confessed to a murder he didn't commit, and watched his daughter's mother begin a life sentence in prison. The last thing he needs is a threat emerging in his marriage, but that's exactly what will happen after he learns that his husband, Sonny (Freddie Smith), has been keeping a rather large secret from him.

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