Jon realized that if he touched William he would become him and get out of this, so he touched him on the shoulder as he as Erin, walked inside
Next thing he knew he was watching Erin walk by him, she walked by and into what he presumed was the master bedroom, he tried to follow her in, but she closed the door while she changed.
Jon paced around wondering what he should do, when the door opened, he didn't see Erin so he walked inside.
Erin grabbed him and handcuffed his hands behind his back.
He got a view of Erin and saw her dressed in a leather catsuit, looking very much like a dominatrix. This was not good, she led him by his handcuffs to a chain attached to the ceiling, damn William and his wife must be into some odd stuff too.
Erin attached his wrists to the chain so he couldn't escape, Jon was in for a rough time...
