Okay, considering the relationship between SM and Heather and the fact that lengthy relationships of any kind, especially of the sexual nature always end up with someone or both people caring. SM called Heather, wanted to see her but she rejected him. She called her roommate and after some time decided in her mind that she did want to see him. She tried the pay phone with no luck, so she calls the cellphone. When the phone starts ringing TM gets very angry. When Heather calls back again, TM tells SM to answer it and go with what is being said and tell her to come see him. He scared for his life, BIG possibility that TM has a gun in her hand, SM tells Heather to meet him at PTL. TM waits for the time it takes for Heather to get there and heads out. With SM cell phone in hand, takes SM truck and doesn't answer the calls Heather is making to SM phone. When she arrives, something happens, something bad. She then comes back to the house with Heathers belongings and body and confronts SM with this. Uses whatever she can to convince him to clean up the mess.
