Once he had his favourite boots back and helped Wheatley get ready, he adjusted the mans gun and double checked the aim before he removed his hand from the portal gun and nodded. If all went well, they wouldn't need two portal guns, usually it had to be lined up just so, one portal would need to be in a specific place and therefore Chelldon should be able to handle it all.

Once he knocked both cubes off the ledge, he leapt off after them without any need for a portal. He put them both on the buttons required before shooting a portal beside the exit door.

"Come," Chelldon beckoned before shooting a portal under his feet and getting spat out on the other side.

Naturally he cleared out of the way before Wheatley slammed into him.
