Jon blushed and looked around conspiratorially.
"Promise not to tell anyone?" he asked nervously.
Karyn's rolled her eyes and nodded.
Jon swallowed and said, "Well you know how I, um, tutor Biff.." his voice trailed off and Karyn's nodded, waiting for him to continue. There was a moment of silence, and then things fell into place for her.
"Biff?!" she exclaimed, "Biff Meadows?" Jon nodded. "Biff the Jock? Biff the womaniser who's dating Sarah McMillan?"
Jon hung his head and nodded again. "He's gay," he replied, "The tough guy womaniser is just an act. Sarah is just a cover. He's not the bone-head he pretends to be; he's actually quite sweet if you got to know him."
