You turn the dials back to reverse Richard from developing as a fungus instead of an animal, but because he's infested Kevin, the watch cannot distinguish them. Kevin instantly regresses into an ape. You shrug, and think well he's going along for the ride. You continue to turn back the dial to the setting you had originally turned Richard back to, at least you think it's the same. A lizard becomes a salamander on Kevin's floor. You then advance the watch to "Normal" setting.
Ew! Richard may be evolved to the same level he was when he was human, but Kevin is now advanced into some reptilian super being covered in a symbiotic sentient fungal coating. Apparently, Richard's memories are intact, and the fungus can speak.
"What happened?"
The reptile thing looks annoyed, but it answers, "Richard you are my symbiote now. Thanks to the primitive insect outside my window." Kevin looks disdainfully (if you're interpreting the reptile's body language as if it were human) around his room.
"The planet is crawling with them," Kevin says with a sigh, "Their petty thoughts hurt my mind."
He extends his hand toward the window. Suddenly, you are violently yanked through the window by an unseen force. The watch flies through the air from your scorched hand and into Kevin's six clawed hand.
"Ah! Now to finish what you started," he aims the watch at you, and you feel yourself falling. Falling off the evolutionary ladder, Kevin takes you to the amphibian stage he had been in, and brings you forward. You evolve into a reptile similar to Kevin, and immediately you try to use your new psychic abilities, but you don't have any.
Kevin laughs, " You don't have any fungal symbiote, I'll share a little Richard with you."
"Huh? Wait- what? Ouch!" exclaims Richard, as the Alien-like Kevi rips a small chunk of Richard off him and attaches it to your crotch.
He orders, "Hold that Richard there until its firmly attached, if you want to develop any psychic powers." He sniffs you, and whispers, "You're cute."
"Huh?" you say staring at the purple eyed Kevin.
Suddenly, your new status becomes clear in your expanded mind, "Oh, shit. Our new species are functional hermaphrodites. There are no males and no females, just tops and bottoms. And you're going to keep me as your mate?"
You swallow hard. Damn, he looks hot, and powerful That think fungal growth on him turns you on the way a silver back turns on female gorillas. You look down at the bit of fungus slowly adhering to your skin. It will take forever to grow, you think.
"Not forever," Kevin answers, "You should have basic telepathy, as soon as it adheres, but it will take decades to get the growth on you that Richard has on me."
"Are you going to make more fungal people like me?" Richard asks. He is sort of pissed that he's an immovable inanimate but living symbiote.
"No, but I will share you with the Reptarian World once I have changed all the humans," he said glancing at the watch, "But I'm going to need something larger to do that. Hm?"
Kevin flips you over and lifts the stubby flap that covers your cloaca. In ancestral species, it was the tail. He proceeds to mount you. His telekinetic power embraces you. You cannot resist.
"When I was human, I always had the best ideas during sex. Now that I'm Reptarian, let's see if it holds true."
"YEOW!" you scream, as Kevin's huge penis emerges from the hidden pouch in his belly, and enters you.
