WHO TO PAIR WITH CASSANDRA AND WHY?

if you think about it in Sims 3 terms, Darren is an Adult, while Cassandra is a Young Adult, so thats a big age gap..

I'd rather send ol Dirk to uni, and have him one day revive Darleen with the resurrecting phone, after he discovers one at uni via secret society. Darren will forget all about Cassandra soon enough, freeing her to find someone considerably more gloomy and gothic.
