There is a side story, where Yeonwoo and Spence visit Josh, they never met Cecil before. Cecil is a very young child, younger than Spence. Iirc at that day Josh dressed Cecil in a pink t-shirt and white short, because he would look cute in it. Cecil didn't like, because he hates pink and it looked like girls clothes. Also Cecil and Pete talked about that Chase sometimes wears womans clothes for Josh.... . Cecil was mad and left. And Spence later ran into him and mistook him for a girl, gave him a motivation speech, told him he looked like a princess ( by the way he also said that Pete looks like a prince...).. and Cecil was so taken by Spence, he got a serious crush on him... . So now Cecil willingly dresses in cute clothes for Josh and Spence, because they seem to like it, while he himself doesn't.
And Pete is at first irritated by it, but I think he later knows the why.

So is cecil josh and chase kid or Graysons child
