Chazwick Thurman/History

Past
Prior to the start of the series Chaz had become an associate of Crimson's criminal organization. During this time he initiated a romantic relationship with Moxxie, Crimson's son. The relationship ended following a failed bank heist when Crimson abandoned Moxxie rather than attempting to rescue him.

Sometime either before or after these events, Chaz had also engaged in a romantic relationship with Millie. It is not known how this relationship ended, only that Millie holds an extremely negative opinion regarding her time with Chaz when reminded of it.

"Exes and Oohs"
Facing financial destitution, Chaz concocts a plan to convince Crimson he has become rich, and to trick him into allowing him to marry into Crimson's family to allow Crimson to acquire his wealth. He succeeds in tricking Crimson, and works with him to force Moxxie to marry him. This plan backfires, with the marriage being put to a halt and Chaz's plans, and lack of any money, being exposed to an incredulous Crimson.

Chaz is killed by Crimson off-screen, with Chaz's teeth and jaw being mounted in Crimson's home at the conclusion of the episode.
