No More Fleas for Fleance, Please

Since this seems to be a blog of firsts, such as, first old man, first chair, first painted pattern, first hoop skirt, first faerie, etc. why not try another first? I have never made anyone really young before, so I thought I would try Fleance from Macbeth. Not really an exciting choice I know, but it will be a challenge. I just had a thought--why not have Fleance recoiling in horror from a rat trying to climb on him? The rat could be symbolic of Macbeth's murderous intentions toward him, one of the weird sisters, or Fleance's innocent role in triggering once again the bloody thoughts of Macbeth. Hmm...thoughts, thoughts...wait, is that a dagger I see before me?
