az bonus chapter theory

do u remember the sjm interview for hofas regarding chemistry between characters and fated mate? she said that sometimes she PLANNED for two characters to be together but then it ends up being like forcing two dolls to kiss and she senses absolutely no chemistry between them. it reminded me of how az and elain were going to kiss in the az bonus chapter, but then nothing happens. maybe sjm planned for az and elain to be fated mates, but when she tried writing it, there was no chemistry! so she had rhys step in between them. that's why it ended up working out with gwyn instead.... who knows! what do u guys think??
