Kenneth Harrison's Links
Rick is one of Kenny's best friends. Even though they didn't meet until they were being trained as soldiers, it feels like they've known each other for their entire lives. Kenny is highly protective of Rick and has feelings he can't quite explain for the man. They aren't dating, but there's something of an emotional relationship there.
Kenny is Rick's best friend. He has few friends or family he keeps in contact with outside of Kenny. Rick has a lot of respect and a deep emotional attachment to the man. After coming home from fighting in a war neither of them understood, Rick took much longer to recover and learn to cope than Kenny did. When Rick was about to go off the deep end, Kenny invited him to stay with him and his family and it quite literally saved Rick's life. Rick has unending respect and gratitude for Kenny.
