Meeting his mate after years made Alpha Nate return back to life. If things were like that, Lara was even more dangerous than Roxy had thought at the beginning.
Losing Lara would have meant dying again for him, and it would have involved the pack the second time around. There's a limit to how many times someone can deal with a broken heart.
Roxy understood that she could not keep the role of the Alpha female any longer. Nate needed Lara nearby, even if not in his bed or home. And the pack needed her next to their Alpha.
Things had progressed without anyone noticing, and they were all linked by an invisible thread.
Still, telling Lara to stay with them forever might not be the best idea... What if she got scared of the responsibility?
Melanie had said to introduce her to the role as slowly as possible, leaving her time to settle down. She didn't say anything about keeping it secret not to let Lara notice, but maybe that was a better option.
