[Cowboy Bebop] What exactly is the relationship between Spike, Vicious, The Red Dragons and Julia?
gpt
Spike and Vicious were members of the R.D. gang. Vicious was gradually getting more powerful in the organization and on the verge of usurping their leader.

Julia was Vicious's girlfriend, but fell in love with Spike and they had an affair.

Spike and Julia wanted to run off together, so Spike planned to fake his own death in a big shootout against Vicious's henchmen and meet with her so they could run off in secret.

Vicious found out about the affair, and told Julia that she'd have to kill Spike, or he'd kill her. Instead she disappeared by herself, leading Spike to think she changed her mind on him.
