That someone who had seen David?
his workplace rival, Bertram Brang.
Bertram was a stout man in his late 30's, with frizzy orange hair, wearing a checked jacket over a white shirt and green sweater with a red tie, brown pants and red shoes.
Bertram had been a rival to David ever since they were at school when they were Becky's age, and they'd been rivals since he'd started working at the office.
He had noticed David's recent change, as he had gone to get a glass of water, and he'd seen David's left hand was 3-fingered, as he saw David leaving the restroom.
He was bewildered.
It wasn't normal for human hands to change to 3 fingered hands... it was all too bizarre!
Later, in his cubicle, he thought over David's bizarre hands.
"I think it had something to do with that tf site..." he mused.
---------------------------------------------------------------
You see, unknown to Becky, Chris, TJ, and Vince, Bertram Brang had overheard them talking about the tf site as he'd dropped off his daughter at school, so he'd heard about the site too.
---------------------------------------------------------------
Now he was intrigued by the site, and wondered if David had been using it. [Of course, he didn't know it was actually David's daughter, Becky, who was actually using the site.]
Bertram thought it seemed good to try out for himself.
so, making sure nobody was watching him, he went onto his computer, and went onto the tf site, and a box showed he needed to register. After he registered, he saw a full body picture of himself on the screen, with his name, details, and all other stuff like that.
With a now apparently sneaky chuckle to himself, he said to himself, "So, if David used this site to tf himself, perhaps I should do the same."
Without a second thought, he set up his monster transformation.
His picture changed to having every inch of his skin become dark blue, his head bald, and his nose as long as a hot dog sausage. His eyes merged into one big eyeball. The picture's body increased in size, and the clothes [save for his jacket] disappared.
AN extra pair of arms sprouted from his hips, tearing through his jacket.
the fingers and toes were more wider, and had dark sharp claws.
he even made sure to have his monster form have big ears, and crooked teeth.
and lastly, he made it so he and only he would see his transformation.
once he was done, A new message box popped up: Initiate Transformation now? Yes/No
"Ummm...I think it already did, but sure." he clicked on Yes.
"It won't be long," he chuckled, "Till i become... the BrangBeast!"
[That was the name he'd made up for his monster form.]
