Wicked Whims "woohoo" end hook

[AntiGM2]

Hi everyone. I need your help.

 

I'm making a script mod that I plan to post on this forum.

 

But since I've never done anything for The Sims before, I've run into some basic problems.

 

The problem: I can't figure out how to detect when "woohoo" ends the kind that's started through the Wicked Whims mod. I found a hook for the start of "woohoo", but I can't find one for when it ends.

 

It feels like I'm looking for a black cat in a dark room, and I'm starting to worry there's no cat in there at all.
