Intertextuality in Alice's Clue

In Chapter 29, Alice and Jasper disappear, leaving nothing but a note on a piece of paper torn out from the book "The Merchant of Venice."
This is symbolic because in "The Merchant of Venice," a character goes and pleads with the authorities to spare her friend.
Alice leaves the note on the page from this book to represent that this is what she and Jasper are going to do for Bella with the Volturri.
At the end of "The Merchant of Venice," the army leaves defeated, just as the Volturri do at the end of "Breaking Dawn."
