His admiration for Triell urged him to help- but he didn't know how. Oliver had never seen the lady, or if he had, he certainly didn't know to put the appropriate rank to her face. He had a working nose, but he had never gotten the opportunity to register her scent either. It frustrated him, how his inability cloistered him into a state of uselessness. The least he could do was prepare for her eventual return- if she returned. And if she did, she could be injured. And that's where he would prove his worth.
Naturally, Oliver hoped that she was alright, and wouldn't need medical attention, but the mind couldn't help but wander. So he did what he could- looked for herbs to increase his stock. However, that was kind of hard when he barely knew how far he could go without walking into danger. What he needed was a wolf who knew the woods.
