Quaz's shirt is like, 5 sizes too big - did he steal it from someone?
He can't have his tools back, though. I carved my name into 'em already.
(( Some backstory: Quaz used to live in Orgrimmar in a little tin shack, in a part of the city with the other Kezanian refugees. It was burned down during the time Garrosh was Warchief and he lost almost everything he'd managed to scrape together since arriving in Kalimdor.
He left for Ratchet in his damaged shredder mech to stay at Trizzip and Jax's place (Trizzip mostly felt sorry for him and Jax just went along with it). Having lost all his money and clothes he borrowed a few of Jax's shirts (Quaz couldn't fit into Trizz's).
Jax had a well-equipped workshop that Quaz also helped himself to, using the space and materials to repair his damaged mech. He prioritised that above getting an actual job, and he was basically just leeching off them and being a crappy housemate (and getting away with it thanks to Trizz sticking up for him). Over weeks, Jax went from barely tolerating Quaz to being openly hostile towards him, especially when Trizz wasn't around, and Quaz was essentially held hostage by his ride being in pieces in Jax's workshop.
Quaz continued working on his mech while trying not to cross the death knight. Then, it all went to complete shit when Trizz went poking around in the workshop and accidentally got his leg sliced off by the almost fully-repaired machine.
Quaz fled in his mech (with a stash of Jax's stuff in it) and Jax went on the warpath, hunting him down and disabling his machine in the outskirts of The Crossroads. Jax tried to rip the terrified warlock from his mech, but Quaz managed to hit him with a lucky chaos bolt from the cockpit, blasting off Jax's arm and setting the area on fire, which attracted the attention of nearby guards. Quaz escaped in the chaos, and it was the last time he ever saw Jax.
The moral of the story is letting Quaz crash at your place might just end up costing you an arm and a leg [insert canned laughter here] :D
(this was all from memory so some stuff might be a little bit wonky)
…Now he's basically flexing on Jax since it's been so long he believes he's escaped all consequences. If Jax actually turned up again he would shit himself, lol. It's thanks to him he has a fear of death knights.
