The actors have undeniable chemistry. TIIC wants Jasam, Liason was a backup. It has always been a back up. It is like OLTL...Jovan has undeniable chemistry...but TIIC wants JOLIE...
As long as the fans watch the show...TIIC is not concerned with making individual fanbases estatic.
You just have to deal with it or turn the channel.
Maybe if Kelly departs Liason might get its chance. But it doesn't take a rocket scientist to figure out that Jasam is the #1 priority. Why else would Liz be stalling on revealing WTD?
Her reasons of 3 months back don't flesh anymore. TIIC is holding the fanbases at bay while the contracts dictate the story.
