In another room on the island, a team of scientists were watching their experiment finish it's process. The government had designed a formula that could physically merge two individuals into one. The end result would be one person with the memories, strength, intelligence, and agility of the two people that were fused. The process took a whole two days to complete, and once completed would last for a total of 6 months.
For now, children were the only subjects that had the highest rate of survival after the fusion. Because of this, the director built this island as the perfect testing center. He thought to himself, "Parents send their children away for months of 'fun', we fuse the children, we do a series of tests for 6 months, and send the children back as they came. Absolutely brilliant." The director sat in his office overjoyed that the first 6 month test of the Strong Man Program was finally under way.
Back in Mark's and Nick's bedroom, the two were beginning to panic as they continued to fuse more and more. Mark's left arm was almost fully absorbed into Nick, and Nick's right arm was almost fully absorbed into Mark.
"Nick, what are we going to do? If this keeps up we will completely fuse together."
"I know, we have to do something" Mark thought for a moment, and then said, "I've got it. We were sleeping naked, so for what ever reason we started fusing together so.."
"So...What?"
"So...I think we only need to put something end between us, and we stop fusing."
"What if we just start fusing with whatever we place between us?"
"Look Mark, we have to try something or we are going to be completely fused together, and then it will be too late." While they were talking, Mark's left arm completely disappeared, along with Nick's right.
"Alright Nick, let's use one of our pillows." Coordinating their movement, they managed to walk over to their bed. Nick grabbed a pillow and placed it between their necks. For a few minutes, they felt a pressure in between their necks as their bodies, or body still tried to fuse. Luckily, the pressure subsided after awhile, and they removed the pillow.
Mark spoke first, "Well I think it worked."
"Yeah," Nick then began moving his left arm over his side of their body.
Mark quickly grabbed Nick's left arm with his right, and yelled, "What were you doing?"
"Hey calm down. I was just seeing what our body looks like now. It's not like we have a mirror in here." Mark let go of Nick's arm, and he too began feeling around their body. They now had one complete body with two legs, one genitalia, one waist and torso, and two arms. Their shoulders were just broad enough so that they could look directly at each other. They both could feel their whole body, but they each could only control their respective sides, Mark the right and Nick the left.
Mark then said, "This is going to be an interesting 6 months."
