On Raine's orders, Calleb went to a neighbouring pack to deliver some documents. He didn't need to do this and could ask someone else to carryout such a menial task. But, his Luna insisted that he needed to meet someone outside of their pack.
Or, more specifically, a woman.
Yes, Raine had been trying so hard to help him get rid of Rossie's memories, despite his great pretense of laughing and joking around with the people in their pack, Raine seemed to be able to see through him and knew very well that he was not okay.
D*mn her for being so sensitive to even catch that!
However, at the same time Calleb was also grateful that someone was able to notice this side of him and this kind of feeling, being noticed by someone, comforted him in a way that he couldn't describe.
Therefore, here was Calleb, entering the said neighbouring pack to deliver the required documents, a labor work that didn't need the Supreme Beta's involvement in the slightest.
