::::::We summarize the information via consensus; ie, what we all agree with the plot. And, as you probably know, References are not required for plot summaries, as they are consensually based. And your post above contains the main difference we are having here. You think the info about what is different between the book and episode is relevant. I do not. I think it is the sort of minutiae that belongs on (and likely came from) a fansite blog. You want the information in, do the work. Do not ask Wikipedia to conform to your novel interpreation of primary sources. 
 ::::::The easiest way to solve this problem is to bring forth reliable secondary sources that discuss the differences. I suspect that the only reason you do not is because secondary sources consider the information as trivial as I do. -
