Origins Characters in Dragon Age 2?

Now i know the chances of characters from Dragon Age: Origins being Party Members in Dragon Age 2 is limited, probably wont happen. But does that mean you shouldnt encounter and interact with them? I think not so I ask you are there any Party Members or other characters for that matter, that you'd like to encounter or (if were lucky) recruit in Dragon Age 2? (Personally im still praying for Shale in Dragon Age 2)
