17 year old Archit was sure about it. The man sitting in front of him was an IDT; an Inter Dimensional Tracker. Those new species were rumoured to exist, but nobody ever saw them. A few sightings were reported in the past few months, but they were never really proved.

Archit shifted in his seat as the train rattled on its way to CST. He was currently between Sion and Dadar. He struggled to remember what he was taught in school about IDT's, it was hard to recall the information, because when you flit between dimensions, the brain tends to forget things.

IDT's were the next generation of tracker cyborgs. With the human ability to improvise and the robotic ability of superfast data processing power, they were almost unbeatable and unshakable trackers on both, Earth and Anti-Earth. If someone really managed to make one, it would be someone with a hell lot of money. And they sure wouldn't send an IDT to enjoy a train ride from Kalyan to CST. So, what was the IDT doing here?

Archit observed the people in his compartment. None of them had a mark- a sort of spiral with a line cutting through it- on them. That meant he and the IDT were the only dimensional travellers. That meant, that the IDT was here for him.

His mobile beeped. It was a message from his girlfriend to hurry up. He replied that he would reach there in half an hour. He then noticed a thing about the IDT. He was operating an Apple iPad. Nothing weird about that. Just the model number. It was an iPad Infinity. The latest model released. But on Anti-earth. That was it; he was going to mind-sweep the IDT now. That would tell him who was the maker of this particular IDT.

Archit started the mental process required to mind-sweep someone. He lowered his defences, and converted his mind into bullets. It was the shape he preferred. As his conscious mind neared the IDT, he felt the light speed of the IDT's thoughts. He just had to get near enough to grab glimpses of the communication that was being carried out.

He put his hand in his bag. His hand curled around the small curved sword he always carried with him. His body tensed in anticipation of action. They were talking about him!

"...right in front of me..."

"...no trails...lead...to...me..."

"...attack...when time...right..."

This was it! The IDT was going to kill him when the time was right. But that moment would never come. Archit was going to kill this IDT. The guys at the university would be pissed off at him for killing a working sample of an IDT, but all Archit cared about right now was about his life. And how he was going to save it.

He mentally chalked a plan. Stealth was not necessary. He would shove the sword in the IDT, preferably in the chest. And then he would return to the other dimension, and report all this. To transport yourself into the other dimension, you just had to jump. The most common way was from a building or the train.

Okay. Time for action. Three...two...one...go! Archit got up from his seat in one smooth motion, and thrust the sword in the IDT. He tossed his bag over his shoulder, and shoving a lot of people aside, jumped out of the train.

Chaos.

Confusion.

"...just jumped out..."

"...for no reason..."

"...put the knife..."

"...man is bleeding..."

"...doctor DOCTOR!..."

"...pull the chain!..."

In the microseconds that Archit took to die, by jumping out of a moving train, he was thinking about how the people at the hospital would react at this news. They never did believe him did they? ‘Dimension travel is just a piece of your imagination.' They said. ‘You are a schizophrenic.' What the hell was a schizophrenic anyway? Must be a good word if they called him that. He smiled and closed his eyes as he hit a pole at 80 kilometres an hour.
