After their fight, Nika and Uriel's relationship finally solidified into something more than friendship, though not in the sense she would have liked. The bond they shared didn't involve any bedroom activities, but they were intimate in other ways.
While Uriel didn't particularly liked the idea of being possessed by Nika and still had a hard trying to wrap his head around that idea, he did feel closer to her. There was a special sincerity between hunters that could only be achieved after a fight. After all, words can be deceiving, but fists don't lie.
Now that Nika finally came clean to him and told him everything he needed to hear, he was finally able to leave what happened in Chichén Itzá in the past and place his trust in her. The same happened to Nika, though the only thing that managed to convince her that Uriel didn't actually want to take revenge on her was the fact that he turned his fist into a palm when he realized how dangerous it was to attack her with his full might.
