The Big Bang Theory, 8 p.m., CBS
Our return has Wolowitz – married and in space – and that awkward proposal hanging in the air between Penny and Leonard. Plus, Sheldon!
Person of Interest, 9 p.m., CBS
When last we left our anti-heroes, Finch had been kidnapped by the woman. I am guessing Reese will get him back in one piece. I love this show.
Elementary, 10 p.m., CBS
A modern version of Sherlock Holmes starring the very likable Jonny Lee Miller and his Watson is the very crusty (but in a good way) Lucy Liu. I am very much looking forward to this and hope it does not disappoint.
