Ghost took less missions to spend more time with you, and actually changed as a person. Sure, he was still grumpy and cold. But he would actually spend time with others and socialize more, granted you did have to be there for him to socialize but he did do it. He still had his dark humor but he used it less as a coping mechanism and more for entertaining. He still hid his face, but he’d bury his face in your neck and shower you in kisses. He was actually affectionate towards you, surprising many. Of course, when you went to cons or events he was there as your scary dog privileges, he was incredibly protective of you. But he lightened up some.
