miles was very serious for a while when they said he was KJ. maybe it was because both of them had the understanding that miles was jb and Alex was kg...cus Alex also looked rather surprised when they called him jb.
and alex was pretty much defending him like, "that's what i mean, if i'm the jerome, surely i'm the other one," and when they ended that discussion you could tell alex was like "i do not agree with that" in his head hahaha
