* There's a comedy relief scene before the big trial where Launcelot, the clown, gets told off by Lorenzo for making puns: "How every fool can play upon the word!" To get some revenge, Launcelot deliberately misinterprets all of Lorenzo's subsequent requests to get dinner ready (told to "cover", as in cover the table, he acts scandalized that Lorenzo would tell him to "cover", as in cover his head, since he's a low-born servant who's not supposed to do that in the presence of superiors). It ends up with Lorenzo laughingly admitting that, okay, Launcelot's not just an idiot--he's got some serious pun skills. At first, the scene doesn't seem relevant to the plot at all--merely a quick comedy sketch. Then you realize that it comes right before the trial scene, in which Portia saves the day using ExactWords. Wordplay isn't just for fools, it seems.
* At the beginning of Act Five, there is a scene of Jessica and Lorenzo expressing their love for each other through classical stories. It all seems very sweet and romantic. But all four of the romances mentioned -- Troilus and Cressida, Pyramus and Thisbe, Aeneas and Dido, and Jason and Medea -- ended in betrayal and/or the tragic death of at least one of the lovers. Not a good sign for Jessica and Lorezo's romance.
