The day before
Based on what Nate was saying, it sounded like he thought all the men that should have been in the second leader's area had been placed in this facility, locked up. It was a crazy theory that if Silver had heard before, she would have just dismissed it.
Right now, with the circumstances the way they were, she was willing to accept this theory.
A leader was allowed to elect who they wanted in their inner castle area. If they wished all of them to be women, then that was the leaders choice. It did not matter how obscure the request was. However, what was more concerning than Nate's theory was the Second leader themselves, Cindy.
Nate's suspicion had become her suspicion due to her ability. All of these vampires having their memories lost, it wasn't too strange as a powerful vampire leader should be able to do such a thing with their influence skill.
