Where they ended up

I was wondering what might have become of the remaining characters after the series ended. Here are some possible ideas:

Nash: After overcoming every attempt by petty officials like Lt. Urbanski to have him fired, Nash runs the SIU until mandatory retirement age or voluntary retirement. He works with Joe Dominguez running Bridges & Dominguez full time and eventually marries Rachel McCabe, who had resigned from the SFPD and returned to the medical field.

Joe:Runs the SIU for a brief time after Nash's retirement, then retires and joins Nash running Bridges & Dominguez full time. The agency succeeds, hiring Pepi and his partner Chet to handle the admin and finances. Remains happily married to Inger and finds himself surprised to be sad when mother in-law Oola dies.

Harvey: Remains at SIU for awhile until accepting a promotion to position with SFPD's Cyber Crime unit. His relationship with his son mirrors Nash's relationship with Cassidy.

Cassidy: Never returns to SFPD. Remains in France and works for her mother. Eventually marries a French police officer who's basically a French version of Evan.

Nick: Passes away from Alzheimers complications in 2005 (same year James Gammon died). Doesn't really "die" in the traditional sense: leaves Nash and Rachel's home with Angel and doesn't return.

Antwon: Recalled to active military service in US Marine Corps after 9/11. Successfully gets epilepsy and PTSD under control and remains in SIU after finally leaving the Corps for good.
