TS2 Players, What Did You Do With Darren Dreamer and Cassandra?

I like all the alternate realities.
I know that I played it out different ways. At least once, Cassandra married Don. But I too thought that Don was a better fit with Nina. And I did think that Darren was the better man for Cassie. I let Dina marry Mortimer after Cassie had moved out. Alexander did not like Dina much at first, but I always made them friends over time.
