Definitely Go to Town
Hee! Snape's silence speaks volumes, as they say. OK, probably not run-on babbling OotP, HBP volumes. Even silent, Snape would be terse. He'd leave the babbling to Potter.
Now Allie, I'm sure she has a plan. She's a Snape!
Speaking of volumes, and going to town - how nice to see you (and others, it looks like) taking off from your art! Let's see now... if a picture is worth 1000 words, then an entire illustrated short art film is worth...
*quick arithmantic calculation*
(subtracts for Snape not speaking, multiplies for his speaking glares)
*rubs hands excitedly*
... more than a metric Gringott's vaultful of stories! *\o/*
