Before Leon entered the room, Jake decided to close his laptop to see if it would stop the change in progress. But Jake could only be hopeful. Leon opened the door to their room. "Hey Jake. Do we still have any aspirin? My head is killing me right now." Jake was reluctant to answer but thought maybe that was just Leon and not the change. "It's in the bathroom cabinet." After hearing that, Leon made his way to the bathroom.
Jake was relived to see no immediate changes like his own. Maybe the change didn't fully process in time. Either way, Jake sighed in relief that nothing- "JAKE!?" Leon was heard yelling from the bathroom. "Oh shit!" Jake hurried into the bathroom.
Upon opening the door, Jake couldn't see anything different. He only saw Leon standing in front of the mirror. "Jake... Don't... Don't freak out..." Leon started turning his head. To Jake's horror, Leon's eye sockets were stretched out. Jake's t-rex jaw dropped to see Leon's eyes were stretching out from his face as he blinked each one individually. "Oh my God." Was all Jake could really say.
The changes continued as Leon felt a weird sensation in his legs. He unbuttoned his pants to see his genitals were practically gone. Not only that, but some sort of slimy substance was emiting from his legs. "Dude, this is unreal..." Leon fell to his knees as he felt his feet change. Slipping out of his socks and shoes, Leon and Jake could see he didn't have feet anymore. Just little nubs with the same substance coming from his legs.
Leon then started to scream in pain as his legs just grew to big for his skinny jeans. Ate Jeans burst in tatters revealing his legs loosing all detail. Leon's legs were now starting to fuze together starting from his used to be legs. With his legs fully fuzed, the entire bottom of his legs started flattening entirely, as he started leaking more slime from his legs... Or better yet, his tail.
Jake stared at the horror Leon went through. His upper body still remained the same. But between his eyes and his lower body, all Jake saw was a slug. Jake's tail started quivering as Leon started slithering towards Jake.
"Jake... What... happened..."
