Adapted from this thread page, stemming from this post on the previous page:

* I may not devise and execute a devious plot with the intent of setting up a foursome between myself, the changeling my character has a crush on, and her two adult changeling children.
** Not even if the idea is for all three of them to be the same person during the deed.
*** Especially not if that's the idea.
*** The two children already sharing the identity in question with their mother on occasion and thereby making my love life difficult is not an excuse for this.
** Executing the "wacky romantic comedy" version of the plan, in which failed Sense Motive checks are used in place of successful Bluff checks such that the whole thing is (in-character) an accident, does not make it any better.
