A new and slightly intimidating side of Sheldon Cooper reveals itself in the preview and stills for The Big Bang Theory season 7, episode 20.

Unlikely as it seems, it looks like the gawky duckling that is Sheldon may be transformed into a swan when The Big Bang Theory season 7, episode 20 airs this week. The episode, titled “The Relationship Diremption” promises a few unexpected emotional conflicts for Sheldon and the geeky gang, and we get a glimpse of the madness in the preview and stills for the episode.

The preview for “The Relationship Diremption” makes it clear that Sheldon’s response to his crumbling relationship with physics is rather on the drastic side.

Well, drastic for Sheldon, anyway.

Though we do have to admit that Dr. Cooper looks kind of cute with that new hairdo; there’s no way the new look will go to his head, right?

Still photos from The Big Bang Theory season 7, episode 20 offer another look at the impending breakup with physics, as well as a glimpse of what Howard, Raj, and Bernadette will be up to in “The Relationship Diremption.”

Though it’s nice to see that Raj hasn’t managed to chase off Emily (Laura Spencer) just yet, the official synopsis for The Big Bang Theory season 7, episode 20 indicates that not all will be well at Thursday night’s big double-date.

Sheldon faces a personal crisis after deciding he’s wasting his time with string theory. Meanwhile, a double date between Raj, Emily and the Wolowitzes ends in embarrassment for Howard.

Poor Howard; but maybe Raj will come off well in comparison? We will just have to wait and see.

The Big Bang Theory season 7, episode 20, “The Relationship Diremption,” will air on Thursday, April 10 at 8:00 p.m. on CBS.

Who do you think will break up on this week’s episode of ‘The Big Bang Theory’?
