In "Quack Fever" the door is finally closed on Nash's lost brother Bobby. Through Nash's hallucinations, we learn about the origin of the 'Cuda, the moment when Bobby gave Nash the 'Cuda. Bobby first surfaced in Episode #39, "Revelations" from Season Three. Bobby was a noble Bad Guy, out to avenge the slaughter of his family (but also to kill a rival drug smuggler). Nash ends up killing the drug smuggler, as he and Bobby finally meet in Chinatown.
In "Quack Fever" we learn that Bobby has just been recently murdered, and that he has a surviving son. The finality of his death, the final proof of Bobby's death is given to Nash at the very end of "Quack Fever" when his son hangs his dog tags from the mirror in the 'Cuda. Only then does Nash grieve.
As we mentioned in the previous episode's commentary, a number of loose ends are being tied up, as it seems like NASH BRIDGES is headed for it's final season. Bobby's fate is sealed, the potential death of Nick is realized, recurring Bad Girl Tamara van Zant is killed off. How about Nash's two ex-wives floating around in Europe? Hopefully we will get to find out.
Cassidy becomes an official bimbo as she contemplates breast augmentation. We don't know if there's any connection to the actress here, but we hope not. The beautiful Jodi Lyn O'Keefe can stand alone without augmentation. As long as we're on the topic of real connections, Jesse Johnson (Don's son) gets to play his nephew. That's easy for father and son, especially if you have as complicated a life as father Don.
