Martin Hart headed up to the roof to take his smoking break, just as usual, but today would be different. Because sitting on the roof today was something that would totally change his life ... and others.
It was Harry's "arrow", which actually looked more like a futuristic-looking gun (hey, ya gotta change with the times). Spotting it near the edge of the roof, Martin picked it up and looked through the scope towards a nearby building across the street. Looking into the scope, he saw some sort of read-out display, which seemed to "lock on" to whichever person he aimed the gun at. After locking on, a short description of the person was shown at the side.
"What the hell is this thing?" Martin muttered to himself.
The person he was currently aiming the device at, according to the information being displayed, was a married woman of 37 years of age. Not realizing what he was doing, he pulled the trigger and watched as the display (which he saw through the scope) changed, informing him that the target had been altered.
"Altered? What does that mean?" he muttered, not even realizing that the next person he shot Harry's "arrow" with would be romantically linked to the woman, both of their pasts changing to make sure that they would have ended up being with each other.
Who knew how reality would change as a result?
