Possible Mistake While Adding

I'm not sure if I made a mistake or not. I had intended for the chapter I wrote for Family Swap to take place after The Guest's episode with Jon and the Kim girls. I'm not sure if I added to the wrong episode, but if possible could the History Of Athena chapter and its child be added after the one with Jon babysitting the younger Asian Sarah and Susan? I do not believe there are any continuity concerns created by them at the moment
