After leaving jail, Víctor is still in love with Elena, but she's married to the former cop -now a handicapped basketball player- who became disabled by a shot from Víctor's gun.
At 1:10:17, Victor's persistence finally pays off and Elena comes over to his house, takes her clothes off in front of him, and fucks him. This is while her handicapped husband is playing a game of basketball. She always watches his game but that day, he wonders where she is. When her husband gets home, he tries to make love to her, maybe getting the feeling that she's straying and wants to show her that he's still capable, but I think she drops the bomb on him and tells him that she fucked Victor.
Prior to fucking Elena, Victor was also fucking the wife of another guy (45:03). Elena's husband took pictures of their affair, and when he finds out that Victor fucked Elena, he shows those pictures to the wife's husband, which results in a tragic end.
