What's Breaking Out of Slytherin's Face?

[erisedstraeh2002]

Has anyone been able to figure out what is breaking out of the statue 
of Slytherin's face?  I think this was in the first trailer, and it 
also appears right before WB aired the preview last Thursday night.  
Someone asked whether Fawkes was in the trailer - do you think Fawkes 
arrives on the scene by breaking through the statute?  I tried 
playing this in slow-motion and I still can't tell what's breaking 
out of there.
