Alright, it was pretty funny when they seemed perplexed, even Albus, as to what was happening to him. Ethan was pretty sure this harmless prank was starting to get out of hand when that weird Ravenclaw kid started jumping in too. Typical.  So, when they started to brainstorm and it seemed that no one knew what the counter spell to Stupefy was, Ethan had to close his serpentine eyes and roll them. Rennervarte, oh my god.

Thinking of how to make his escape, Ethan suddenly reared his hooded head up and slid into the crowd, his scaled, serpentine form allowing for much greater control, allowing him to slither with surprising agility into the small gaps between the group, looking to flee by their rear. Of course, annoyed by the Ravenclaw boy's proximity to his cousin, he decided to flick the massive length of his snake's tail to hit the boy on the chest on his way out. With him out of the way, he seemed to be free to duck around a corner, morph back, and go on his merry way.....

But his back was exposed, and he had no way of looking back, so if someone were to stun him...
