After last week's episode, the geeky gang is back with more of its wacky antics and nothing short of familiar humor. However, it seems Sheldon Cooper isn't at all going to be as humorous when the all-new episode airs. In fact, he admits that he is actually very depressed after knowing that his string theory is apparently futile. Moreover, Sheldon might be failing his first love physics and we are hoping that it's not really the end between him and Amy. Now because of his excessive depression, Sheldon is going try out a variety of coping mechanisms, but we're not really sure if he is doing the coping or the mechanisms do it for him.

A sneak peek to Big Bang Theory season 7 episode 20 titled "The Relationship Diremption" shows Sheldon making some more significant decisions in his life. At least that's what he wants us to think. We can even see Sheldon trying to explain everything to Penny and the latter rapidly learns the real meaning of the phrase 'No good deed goes unpunished." The preview also hints that Howard, Bernadette, Raj and Emily are going to enjoy a double date, but things will take a different turn from there. It can be noted that Raj was actually surprised on Emily's reaction when he confessed that he is also seeing his old girlfriend Lucy. So is this, in any way, related to what is to come among th four? Find out by tuning in on CBS tonight at 8/7c. Watch Big Bang Theory season 7 episode 20 stream using the free online stream link at the end of this post.
