NCIS: Los Angeles will take part in a crossover episode during season 6, but it won't be with either of its NCIS brethren. Instead, the drama will visit CBS' Scorpion.

A freshman series set to air directly before NCIS: LA's new Monday night timeslot, Scorpion will receive a visit from the Office of Special Project's Hetty Lange (Linda Hunt), according to Entertainment Weekly.

The news comes as a surprise to many, considering a crossover with NCIS or the brand new NCIS: New Orleans seemed far more likely as the Shane Brennan series heads into its sixth season. Scorpion's Walter O'Brien (Elyes Gabel) and his crime fighting geniuses will need Hetty more, however.

Despite her current troubles on NCIS: LA, Hetty will drop by Scorpion for a Halloween themed episode at the end of October. When a priceless piece of artwork forces O'Brien's team to head undercover at a Halloween party, the leader will call in Hetty to give his crew of intellects a few field work pointers.

Catch up with Hetty and O'Brien when NCIS: LA returns at 10 p.m. ET on Sept. 29, and Scorpion makes its debut at 9 p.m. ET. Click the video below to see a preview of NCIS: LA's next episode, "Deep Trouble: Part 2."
