Dennis Nedry, caught up while working on his computer inside the InGen Office alongside Ray Arnold, had to find the perfect moment to sneak away. He couldn't sneak off JUST like that.

When everyone was away, he himself shut down the security program. Soon after, he got in a Jurassic Park Car he found, and started his journey towards the laboratory that held the 'special tools'—The Dinosaur Embyros.

After he got there, he disactivated the cameras. And grabbed the Embryos—suprsingly, in a modified Barbasol shaving cream can.

After that, he got back in the car...

...

The bad weather and hard raining got to him. He soon got disoriented from the road, which ended up with him stopping his car to calm himself down.
