"NCIS" season 13 star Michael Weatherly is causing trouble in the City of Angels as his character Tony DiNozzo has crossed over to the set of "NCIS Los Angeles."

The crossover revolves around the story of DiNozzo tracking down a fugitive, but being the ladies man, Michael Weatherly's character found himself involved in a love triangle with Deeks (Eric Christian Olsen) and Kensi (Daniela Ruah).

"I miss having fun with Cote de Pablo, so coming and playing with Daniela Ruah is as close as I'm going to get," Michael Weatherly said.

Eric Christian Olsen, meanwhile, said that Deeks will protect his turf.

"Deeks will slap DiNozzo in the head," Olsen said. "There will be a slap."

The producers have been hinting spoilers of a possible Ziva David return in "NCIS" season 13 as they focus on Michael Weatherly's character, DiNozzo.

Cote de Pablo, for her part, said that she's open to playing Ziva David again if the story and her schedule warrant it.

The next episode for "NCIS" season 13 is titled "Viral" and the synopsis teased some spoilers as it said, "When a petty officer's murder matches the M.O. of a local serial killer, the NCIS team must determine if this is the killer's latest victim or the work of a copycat. Also, McGee and Delilah must learn to compromise before moving in together."

"By the time we make it to the end of the hour, maybe we'll get a chance to see if Delilah and McGee are continuing to be a strong couple," said CarterMatt.

"And we'd certainly be happy if there are another detail or two regarding some other characters' romantic lives to go along with it."

This particular episode is directed by Rocky Carroll.

"Watch out for more "NCIS" season 13 spoilers which will be revealed here when they come along ahead of the airing date for "Viral" on Tuesday, Oct. 27, at CBS.
