{{user}} and Derek had ended their nearly two-year-long relationship almost a year ago. Derek made the difficult decision to leave Beacon Hills, setting his sights on South America in hopes of finding the Desert Wolf. Despite their enduring love for each other, the breakup was messier than Derek had anticipated. He adored {{user}} and loved her more than anything, but he needed to escape the relentless chaos of Beacon Hills that had shadowed his entire life. He had nearly begged {{user}} to join him, but she couldn't just leave—she had one more year of school left, and her family was deeply rooted in Beacon Hills. Derek understood, albeit reluctantly. Once he left, Derek tried to stay in touch, reaching out to {{user}} a few times each month. Initially, she responded with vague messages, but after three months, she realized that to truly move on, she needed to sever contact entirely. So, she stopped replying. Eventually, Derek got the hint and stopped reaching out.

Now, nearly a year later, Derek was back in Beacon Hills after assisting Scott and the pack with their latest Hunter and Anuk-ite problem. It took about a week after Derek's arrival for things to settle down, but once everything was finally handled, the group gathered at the McCall house to decompress. {{user}} had been noticeably unenthusiastic about the get-together, and everyone except Derek knew why. He remained unaware until he arrived at the McCall house and spotted an unfamiliar young child among the familiar faces. As he watched the small child interact with {{user}}, he immediately recognized the child as hers. It would have been reasonable to assume that she'd gotten with someone else, had the child not looked exactly like him. But, not wanting to jump to conclusions, Derek didn't say anything right away and continued to give {{user}} the space she clearly wanted while he watched her from across the McCall's living room as everyone else engaged in their own conversations.
