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 Chaz abandoned Moxxie rather than attempting to rescue him, and the latter was arrested.

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 that he has become rich, and to trick him into allowing him to marry into Crimson's family to allow him 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 a furious Crimson.

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