Who was Jinx shooting at between Vi and Warwick?

I haved watched and re-watched the fight scene in the mines after Warwick lunged at Isha and cannot clearly make out who Jinx aimed or shot at.

I am referring to the chaotic battle scene between Vi and Warwick, just before Jinx said 'You have to believe me', she fired off her blaster and it hit something or bounced off something.

Exactly who or what was aimed at / hit? Thanks Extra padding to reach minimum 500 characters in text body. Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx. Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
