Emily is a middle-aged white lady and Rex's mother.
Rex just isn’t accustomed to so much resistance. We try to keep our interactions really positive and we don’t use the No word.— Emily
Emily is a typical helicopter mom, arriving whenever Rex has done something abusive to Desi in order to shield him from retaliation. Being under Rex's control, this ultimately culminates in her protecting Rex while John shoves Desi outside and locks her out without her inhaler. Emily then watches with Rex and John as Desi suffocates to death, from an asthma attack.
