It's one of those things; you just get a very nice stroke from being included in the next thing.
It's just a logical guess that they are very very wise to put someone from the old series in it, and if you had to choose, it would be a very difficult decision.

Well, you know, what's better? To play a character who stays stuck in the same baggage year after year, or to play a character who gets beyond that and goes to a new level?
You're only as good as you are now - not as good as you were before.
Not that I wouldn't have been equally happy to see the old buddies and see it all start up again that way. But this was more of a work situation, and a very good one.
