Or maybe satish was covering for his brother and posting as him. He had to have known they needed cover. I've even had the passing thought that the kalpoo mom was posting as depak.
Well Deepak is older and Satish is closer to Joran's age. Maybe Deepak was home on the computer. Maybe he was willing to be pulled into this because Satish was with Joran and because they had Deepak's car. Who the other person was is still a mystery. We have a Gardener who probably can say Joran was in the driver seat and there was 2 other people in the car, but it sounds to me like the Gardener cannot say for sure which Kalpoe brother was in the passengers front seat next to Joran.
Maybe Satish drove Deepak home and dropped him off. Maybe Satish did drive back alone to get Joran after Joran asked for a ride by text message.
