Dan couldn't take the strain, so he/she got up while Brian was still on the phone with Dan/Vicky and got dressed.
Brian was so busy cussing out Dan that he didn't notice until Vicky was walking out the door.
"Hey babe, come back!" Brian called out.
The real Vicky, in Dan's body, heard Brian say that and hung up the phone.
Dan made it out of the place and down the street before Brian could get dressed.
Dan felt sexually flustrated and angry at both Vicky and Brian. This thing had to chill for a while so Dan could figure things out. Maybe if I just dissapeared for a while, Dan thought, and let things cool off, maybe then I can figure things out and be able to fix things.
But things only got worse.
