Bros before Prose...or Hoes...or Hose...

So, while scanning out my lines I noticed that in the middle of the first scene Proteus switches from Verse to Prose after a rhyming couplet (line 75). I think that he is trying to leave Speed and exit since his business with his loved one (his Bro, Valentine) is concluded, but Speed distracts him with the sheep rhetoric. It isn't until Speed has left that Proteus goes back to Verse.

Also, this isn't the most academic website, but they can't all be wikipedia, right? It's the Bro Code, which the Proteans and the Valentineans might find interesting/useful: http://jigarbpatel.blogspot.com/2008/12/official-bro-code-part-1-articles-1-40.html
