Well now wasn't this nice? It looked as though he had gained another ally in the tower. Although he currently did not know to what extent that this woman may go to achieve her goals. Preston did know that she could be very helpful to him in the future. And may even prove to be a good friend as well. Given that they had essentially offered each other mutual protection.

"A-ah, alright then..." So what was he going to do? Probably just do the same. But before that, he had a feeling that he may need that gun that he was granted sometime in the future. Meaning that Preston may need to assemble it sometime soon. "We will find a way out eventually." Or bring the tower crumbling down...or both. It just depended on which one came first.
