The sound of a shotgun could be heard from behind the Faunus woman that was engaged with the Ursa and a sight of Nyte quickly running towards the Ursa with briefcase in hand could be witnessed. It was true that he had previously believed his inability to take on any Grimm that was the size of an Ursa (or larger), but he had to find Ash and find him quickly. Besides, this woman had helped them find Soleil and that meant that he owned her a debt. It was also more than enough reason for him to believe that likely she was telling the truth regarding Ash's whereabouts and the fact that he was nearby. 

Once closer, the raven swung Prometheus with all of his might and slammed the briefcase onto the Ursa's side before jumping back and sending a few more shotgun shells in its direction. "Are you alright over there?!" He was referring to the unnamed Faunus woman who had taken charge against the Ursa and not Phoenix who had kept his distance from the battle while holding Soleil against his back. 

"If you're injured, then step back!" The raven held out his trusty weapon and partner-in-crime. ". . And I can distract it while you run!"
