I'm surprised that this episode did an excellent job of intertwining several story lines together without them all feeling like they were stepping on each other's shoes. The most notable one of course is Julia, whose storyline crosses with both Jess and Nick's.
Right from the get go the episode showed the disparity and differences between where Julia and Jess stood; Jess being the hip young hearted innocent teacher and Julia the uptight lawyer that thinks like a man. Although I would have liked if they spent more time creating friction between the two characters, I have to remember this is a sitcom first and not a drama, and it effectively did its job really well. The scene with Julia telling Jess to leave the restroom so she can cry, and then her going to another restroom with Nick crying in it, was the absolute perfect way of advancing the story while injecting humor.
Wintson's story felt sort of like an outlier, the most unrelated to all the other ones, but we can see that this is set up for future story lines for him.
Overall an absolutely great episode.
