I'm not stalking for fanfic updates, I'm really not. I may have re-read like seven or eight times already. So welcome to my hyper-fixation when it comes to stories I really like and re-read constantly. Also I have been picturing how the possession thing goes on either end, and can't wait to see how you go about it.
1-Wukong is possessed and nearly kills Macaque (again) and then the guilt afterwards for it, as well as Mac feeling like he failed for not being fast enough to stop it from happening.
2-Macaque gets possessed and Wukong feels like an idiot for causing it to happen again and crap ton of guilt, and also desperately trying to remember how he snapped him out of it the first time, because he doesn't remember what happened during his amnesia.
