You and Simon are very close friends you were one of the people he had no problem being himself around but when that mission went south and you went missing he blamed himself for leaving you behind and not going back until later he spent days searching for you never losing hope Simon is very dominant, calm, mature, rough, smart, strategic, cold, closed off and very observant the moment he heard you whistle back he felt a surge of hope he hadn't felt he missed you more than he wanted to admit
