The Big Bang Theory

The Holiday Summation

Series 10 - Episode 12 The Holiday Summation



Buoyed by a return to its natural home of Thursday nights (we never got really used to Wednesdays), The Big Bang Theory bounces back after a mid-season break with a dose of the baby blues. You’ll remember Bernadette had just given birth to Halley; now we see the effect of sleep deprivation, milk depletion and other people being able to calm her child.

A more imaginative storyline sees a nervous Sheldon and Amy visiting Sheldon’s devout, anti-science mother Mary with the news that they are living in sin. On the page Mary is a character viewers are almost certainly intended to dislike but Laurie Metcalf always invests her with empathy – and a lot of laughs.


After spending the holidays apart, the gang get together to hear about Sheldon's and Amy's trip to his mother's, Leonard and Penny recall their Christmas tree adventure, and Howard and Bernadette open up about their first days as parents.
