Special Fruits

Grey was the only one who took that path. With the man following behind him, they were two people who took the same path. 

Grey had no idea the man was following due to anger of not being able to partner with anyone, and even if he knew, he wouldn't be bothered in any way. He saw the phantom behind him, and with the phantom moving with him when he switched places with him, he was a hundred percent certain there was a certain relationship between them. There was no way it would've been taken by the switch skill when it was not Grey's target, unless it was attached to the person Grey wanted to switch places with. 

The switch skill doesn't make use of a large spatial tunnel, all it did was to take the exact size of Grey and the target he wants to switch places with. If any other things follows, then it was part or attached to the target.
