As soon as Vincent saw Valeria walked out from the library with the sad look on her face that's when he entered inside.
He knew the atmosphere inside the library was not normal and that's what he wanted to happen. He knew his wife will be at her low this moment and he wanted to use that as an opportunity to poison her mind against them.
He had finally brought his lord out from that sealed realm and now he wanted to serve his lord by fulfilling his orders.
His eyes search over the whole library when he found his wife sitting in one corner. She had her eyes focused on a particular direction as if she was in deep thought.
Vincent smirked and walked towards her putting back his worried face.
"What are you thinking love" his words broke her gaze and she instantly lifted her eyes up to see Vincent looking her with a smile.
