Liza has a lot of work to do.

On Wednesday's episode of Younger, titled "Getting Hygge With It," Liza (Sutton Foster) continues her valiant efforts to mend her fractured friendship with Empirical partner, Kelsey (Hilary Duff), after she revealed she was much older than she was pretending to be.

In ET's exclusive sneak peek, Liza pulls Kelsey aside during a work party after noticing Kelsey's on-again writer beau, Colin McNichol (Jay Wilkison), pushing Kelsey aside and trying to pitch her boss, Charles (Peter Hermann), his book.

"Of course I care about you very deeply. That's why I want to see you with a good guy," Liza tells Kelsey, before listing all the reasons why her "relationship" with Colin isn't ideal. "You deserve better. You deserve someone who treasures you, who opens doors and walks on the outside of a sidewalk."

"What kind of old lady, lace curtain handbook is that out of?!" Kelsey spews. "Stop pretending you have a clue about how I think or who I am. You know nothing! You don't even know what a meme is!"

Duff spoke with ET recently and explained where her character's mindset has been since Liza dropped the truth bomb on Kelsey.

"Kelsey is protecting herself right now and she is really damaged and feels really betrayed," the 29-year-old actress told ET. "She's not living with [Liza's ex] Josh to get back at Liza, I honestly think she needs a place to live and they have that conversation in the bar and they're the only two who know what they're going through. So they're finding comfort in each other and they're also commiserating a little bit and they're finally building a friendship. Maybe lines get blurred. Maybe there's a gray area. We'll see."

Younger airs Wednesdays at 10 p.m. ET/PT on TV Land.
