"The Good Wife" season 7 Episode 18 sees the return of "Pitch Perfect" star Anna Camp as lawyer Caitlyn D'Arcy, while Connor is making a last ditch effort in his quest to take down Peter Florrick.

Apparently, Connor has something on Eli's daughter, Marissa, and he's using it to blackmail the latter into doing something for him.

The choice is fairly easy: help Connor take down Peter, or else.

Meanwhile, the sparks will fly between Caitlyn and Alicia once again as Anna Camp returns on episode 18, according to "The Good Wife" season 7 spoilers.

Fans of the series know that Caitlyn is the niece of David Lee who grated on Alicia nerves right from the get go. She has proven to be a good lawyer but her career was cut short when she got pregnant.

Caitlyn decided to leave the firm to raise her baby in the episode "Long Way Home," just when she got a promotion. So it would be interesting how Caitlyn has been doing all this time, and how Alicia will react on her return.

This would be the final season for "The Good Wife," and the final episode has already been announced for May 8.

The synopsis of "The Good Wife" season 7, episode 18 teased spoilers as it reads:

"Alicia and Diane defend the privacy rights of a therapist whose neighbor, represented by attorney Caitlyn D'Arcy (Anna Camp), flies a drone over his home office. Also, Assistant U.S. Attorney Connor Fox (Matthew Morrison) attempts to use Eli's daughter, Marissa, as leverage in the case against Peter, and the power struggle at Lockhart, Agos & Lee reaches a boiling point."
