You can check out some spoiler details on their budding relationship below, via showrunner Liz Meriwether (right after you metaphorically lynch me for that accidental pun).
"She's really funny and we really like her," creator Liz Meriwether says, noting that because Jess/Nick and Schmidt/Cece are hitting bumpy roads ahead, the romance quotient on the show will, for now, be filled by Winston. "She's tough love for him, which is fun and gives it back to him pretty intensely. She's almost like a coach for him."
So yes, in case you were wondering, Brenda Song will be back for more New Girl episodes. What did you think of her character in "Cooler", and are you excited to see more of Winston's new romance with Daisy?
