I love him enough to let him hate me.
Travers McLain is Edie Britt's son whom lives with father after Edie gave him full custody.
Travers McLain is the son of Edie Britt and Charles McLain. Edie and Charles were newly weds and they decided to have a child. Edie and Charles divorced shortly after and Edie gave Charles full custody because she wanted her son to have a normal life. Due to this, Travers resented his mother.
When Martha ran into Susan at the supermarket, she mentioned that she was looking after Edie's son for the night because Edie was spending the night with a man, it is assumed that this is Travers she was talking about because he is Edie's only known son. That night, when Edie's house burned down, Travers was not seen with Martha Huber in the crowd of people, so it is assumed he was either with his mother, or still in Martha's house. ("Pilot")
Initially, Edie used Travers to get closer with Carlos but Edie soon feels that if Travers lived with Edie, Carlos would come and visit more and, in the future, settle down with her. Edie starts to fight for Travers's custody, but Carlos feels it would be unfair to Travers if he wants to see his mother and his father. Travers returns home with his father. ("Into the Woods")
At the end of season 4, Travers receives a phone call from Edie saying that she'll be staying with him for a while. ("Mother Said")
After Edie's death, Susan, Gaby, Bree, Lynette and Karen travel to Travers's prep school to give him Edie's ashes. Travers refuses and heads off to class, but not before Karen tells him that Edie loved him and she was looking out for him because she knew she would be a bad mother. Travers then becomes upset about Edie's death, but tells them that they were Edie's closest friends and they should spread the ashes how they see fit. The women then spread Edie's ashes over Wisteria Lane. ("Look Into Their Eyes and You See What They Know")
