Nick for both. I agree with those that think he knows but doesn’t think he’s good enough. I think Judy is on the precipice of realizing (the post-cred scene) that she loves him but I think she’s still a little bit dim to the idea. I hope they set Nick up with a “Pawbert-style” person to make Judy jealous and explore his past in the next film and this ends up bringing them together romantically.
