"You..."
Steve whispered and tried to move his arm, but was unable to do so because the straps of the belt had fastened his hands to the table and he couldn't even move his wrists completely,their mobility got restricted. He got completely apoplectic at this response of Mark.

" Don't get furious, my friend. It's just what people like you deserve."
Mark said with a feeling of satisfaction on his sadistic face.

Steve wrathfully glanced at Mark and suddenly the expression on his face changed and with a look of curiosity he asked
"Have you tested this complex on anyone yet?.."

"Just on mice"
Mark replied and went off to his desk and scrutinized it. After a moment he picked up a syringe in his hand and held it high as if he has won some sort of award.
"But certainly I'm going to test it on a human subject ,today"

Steve noticed all this and the other moment he reckoned what Mark might be planning to do. Steve wished that he never would have picked up her (Vinnie's) Call and he would not have been here.

Mark started heading towards Steve while holding the syringe high in his hand.Slow tapping sounds echoed the lab as he walked towards him.The old man was still there witnessing all this in utter silence and he kept on holding the stick all this time.
I don't know why -_-

Mark stopped near the table where Steve was lying impotent to resist any harm done to him.

"I still have a question,Mark...'' Steve said

"What is it?" Mark demanded

"No doubt you're going to inject this mutagen complex into my body to perform your hellish experiment. How you're going to take revenge from everyone else? Are you going to bring everyone out there one by one into your lab and then introduce it into their bodies?
You are a petty idiot if you think so"

"Ha ha,you think I'd plan something like that? My thinking starts where your mind stops thinking,Steve"

"What are you going to do?" Steve asked with a look full of anxiety.

"Vector" Mark responded

"What? What do you mean by that?" Steve demanded.He realized that this was not all of what Mark has got.

So far it seems like Mark is a kind of guy who never runs out of the plan. Let's see what is he planning to do next.
