Deer/Fauna is the main caretaker/mother figure Meta had when he was a child. However, he was forcibly taken away from her when he was young. Meta could normally control his feelings regarding her, but due to becoming a parent himself by looking after Star, similar circumstances which to how he’d been adopted by Deer, those memories resurface and he struggles to control his sadness for being separated from her. Deer herself was a very dangerous and fearsome individual who always used violence to solve problems rather than words. This behaviour partially spread to Meta and he’s conflicted regarding such things due to it being the last part of her he has.
