Where are Shawn D and Belle?

So, all of Belle and Shawn D's parents have died, but at the service on yesterday's episode, excuses were made for every family member except them.

Even recently, when Bo was near death, they spoke of Zack and Siera, but never mentionned Shawn D.

I've been hoping for their return for a while now, but I think my dog is dead, because the writers and producers seem to have forgotten about them.

Ah sucky poo.

What about you? Are there any characters that you miss?

*edit* Of course, I posted this and then went to watch today's episode.  Belle and Shawn D. were mentioned.  No hope of them coming back though, because they conveniently get to know the truth.
