Ash couldn't help but try to think back to the moment that the male was knocking on the door. 'Was there anything special with the timing of his knocks? It was not like he spoke up to announce who he was or anything.'
She couldn't help but wonder if there was some form of password or something else that was in place to allow people entry.
There were no words spoken by the male so it would have been difficult to identify who was on the other side of the door before it was to be opened up.
Cal and others might have been already expecting visitors so they responded quickly but that was still quite carefree of them to open the lock without knowing who was knocking.
The only conclusion she could come up with was that they were most likely using a certain method of identifying who could be allowed entry.
That method would only be known to those who were allowed inside and if they were smart enough then they would change the method of entry frequently.
