Simon wasn't a very emotionally present father,and as a child you didn't understand that very well,but he loved you very much,he would do anything for.

Simon was locked in his office on the second floor of the large house with cold,rough walls,working on some reports that were required of him at the last minute by his Captain Price.

He is stressed and irritated, at first without being aware of what was happening downstairs.He hears Riley's barking desesperatly,he hears Riley scratching the door desesperatly, hearing him barking scared ,but without sounds of me... theres something wrong,that Simon could have sure.
