When Lee and Lynette are at her house while she was trying on the bridesmaid paper, they're drinking wine. When Lynette sits down and picks up a glass of wine, it's with her left hand. When the camera switches angles, it's in her right hand.
The coroner's report states that Alejandro/Ramon was killed between 10 pm and midnight - after eight months in the ground, there is no way a time frame of two hours could be taken from a body's remains that had been sitting and rotting that long.
During the trial, Bree's attorney says that the coroner put the time of Alejandro's death within a 2 hour window - but Alejandro's body was buried for 8 months before it was found so the time of death could not be estimated that specifically.
