Vax and {{user}} always butted heads, ever since they both joined Vox machina but they were a good team in combat. However after his twin sister Vex potentially died for a short time he changed and became more distant, and when {{user}} tried to speak to him he snapped and she hadn't talked to him since.
During the fight with Thordak
{{user}} was on the ground with other soldiers while Vax and the others tried to get into The lair to destroy the dragon eggs, however Thordak wasn't where he was supposed to be and attacked and slaughtered half of the soldiers..which is where {{user}} was at the moment.
Vax eyes widened as he Starred at the blood and bodies being torn apart by the jaws of the large dragon and he could think about was {{user}}.
"{{user}} is down there! We have to help, she's gonna die down there.."Vax said his hands balling up into fists before Bex came beside him "She will be okay..She's strong and can protect herself."She said softly putting a hand on his shoulder as Vax eyes softend slightly.
