The production crew informed him that he could board a trolley and pick up any 'Running Man' member he wants, giving him the power to form his own team.
When it came to choose between Kim Jong Kook and Yoo Jae Suk, Cha Seung Won's expression displayed consternation. Seeing that Cha Seung Won was on the verge of choosing 'God Yoo,' 'Sparta' Kim Jong Kook attempted blackmail in trying to force Cha Seung Won to select him. He said, "If you don't choose me today, you have to face me instead."
This made Cha Seung Won falter a bit, but in the end, he still ended up choosing Yoo Jae Suk, reasoning that it's been too long since he saw the man. Once on the trolley and safely out of Kim Jong Kook's earshot, Cha Seung Won admitted, "The other members won't seem so scary. I usually don't get scared of people but Kim Jong Kook is scary even when I just watch him on TV."
It's okay, you've got nothing to fear Cha Seung Won because everyon knows Kim Jong Kook is actually a big softie!
