CSI 13.08:
CAPTAIN ROBINSON is a Seattle police detective and also Finlay's ex-husband, who knows she's back in Seattle to cause trouble for a man linked to the bodies in a Nevada mass grave. Robinson has learned to handle Finlay delicately while still maintaining control, and though he admires her tenacity, he's wary of her hot-headedness. Robinson works side by side with Finlay to bring in serial killer Tom, and in the process it's clear the two still have feelings for each other.
Is this going to be an episode entirely in Seattle with Finn and "callbacks" to the lab for a glimpse or two of the others?
Maybe, or like Cello and Goodbye with a couple going and the rest staying
