The Big Bang Theory

S10-E12 The Holiday Summation

S10-E12 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.


The comedy returns after its mid-season break. The gang hear all about one another's Christmas adventures, from Sheldon and Amy's terrible trip to Texas, to Howard and Bernadette's first days as parents.
