You enter his home, and it's impossible to move.

A simple theft, standard procedure mimicking a "rescue" of the goods from the couple's home, this time a key code access to some dark matter they farmed up at CERN. We sent the robot first. A housefly, no bigger, flying through the air at a realistic speed and awareness. Completely indiscernible from the real thing. The couple were asleep, with the key most likely being found under his keys in his wallet next to the bedside.

Our agent went in. There was a vent on the outside of the bedroom leading up to the second floor. He snuck his way up the wall, then emerged from the vent and felt cat-like to the ground. Something went thud, and we got the panic signal. Visual gave us the image of a still figure, curled on the ground next to the bed. Our agent apparently couldn't move at all.

Opinions raced, from a live enemy agent having shot him, making him paralyzed, from suggestions of an energy field seizing his muscles. It seemed nobody could agree what had him wrestling on the ground, blowing the panic button as soon as he stepped foot inside. The couple squirmed in their beds; it seemed on the the causal link between the man and the codes was in effect. Something about the universe didn't want our agent to have those codes. We suggested an abort, and he was freed, having exited the time-causal chain leading to him finding the chains. He exited using a window and his multi-tool to silently abort. He reported a sensation of excruciating agony while in the time-causal loop. The black hole would be ours soon. Later, but soon.
