'The Good Fight' Sneak Peek: Colin's Mom Surprises a Pregnant Lucca With an Unexpected Visit (Exclusive)

ET exclusively debuts a first look from Sunday's episode of the original CBS All Access series.

Mothers know best?

On Sunday's episode of The Good Fight, Lucca's (Cush Jumbo) pregnancy begins to affect her job at Reddick, Boseman & Lockhart and she gets a surprise visit from Colin's mother, Francesca (guest star Andrea Martin), which throws her completely off her game.

In ET's exclusive sneak peek from the episode, Lucca -- who's with a client in her office -- sees Francesca dropping by the law firm unannounced out of the corner of her eye. Distracted by the unexpected presence of Colin's mom, she excuses herself from her meeting to see what Francesca wants.

"Is there anything I can help you with?" Lucca asks, slightly exasperated.

"I have a present for you, as a thank you for my recent encounter with the police," Francesca says jovially, handing Lucca a nicely wrapped present, a signifier to Lucca that she somehow found out about Colin being the father of her baby. (The gift, by the way, is quite memorable!)

Unsure how to react, Lucca advises Maia (Rose Leslie) to check in on her client, who assumed she was stepping out of their meeting for a bathroom break. "And tell him I'm not going to the bathroom," Lucca firmly reminds Maia to say.

Of course, Francesca has to have the last word. "Very nice meeting you," she tells Maia. "I think your dad stole some of my husband's money. It's a good thing. He's an a**hole." Watch the exclusive sneak peek above.

New episodes of The Good Fight are available to stream Sundays on CBS All Access.
