Nodding to when Knox told him and Sophie about the application of the Caterwauling charm. When it was used on Hogsmeade. It was pretty awesome, how large of an area this spell could use.

Back to the spell. Its seems that all you had to do was trace the outline of the door with your wand and cast the spell. Nigel would love to try this on his house when he gets back home. But it would be too time consuming. Since it is pretty big and he would have to do it all by himself.

"in-TROO-duss con-COO-shee-oh, Intrudus Concutio". Okay that was easy enough to pronounce and say. So...Who was going to cast the charm first. Nigel did not care either way. Nigel looked over at West and asked "You want to cast Intrudus Concutio first?".

Nigel was not to thrilled with hearing the alarm blasting in his ears. But this was interesting.
