Murdoc very nearly shudders while he watches the two near duplicates interact with one another. He takes a deep breath to calm himself, straightening in the seemingly likely event that Kurloz cannot control...well...himself.

He keeps a careful eye on the situation, but he doesn't want to step in so quickly. Kurloz is understandably taken aback, but he knew what he was getting into. He had said he had understood and so he would be given a fair chance to take initiative.

He takes note of the mouth binding. A cunning trick, but not as it should be. He cringes as the boggart easily rips through the spell, knowing it would not last. He won't watch any longer, so he steps forward and casts the Riddikulus charm wordlessly and seemingly, with ease. It takes a good deal of focus and concentration. Something Kurloz will have to master, given his situation.

He sends the boggart backward into the cupboard and seals it shut again, turning on his heel to face Kurloz.

"You need to act much faster, lad."
