Bobby Rivers wasn't aware that he was Thomas and Anna's father until they were fifteen years old. It was certainly a big shock at first but as we head into Season 3 we find that he is handling it nicely.
Just how must he be feeling then when seventeen-year-old Billy arrives on the scene and announces that he too is Bobby's biological son? "Stunned" is probably a good way to describe it! As for the rest of the family, most particularly Thomas and Anna, 'stunned' doesn't even cover it. What is surprising for Thomas is how tough it is for him to see Bobby and Billy getting along so well, doing things together and generally enjoying each other's company. Could it be that Thomas is jealous and that he cares for Bobby more than he lets on?moreless
