A new promo for this week’s episode of The Big Bang Theory revisits an old rivalry and shares a Sheldon pushed to the limits of his self-esteem and his imagination.

CBS has released a fresh preview for “The Habitation Configuration,” which will air Nov. 8 at 8 p.m. The promo drops hints of a “big fight” (probably between Sheldon and Amy) leading to another (almost certainly between Sheldon and long-time enemy Wil Wheaton). Check out the video below!

Why are Amy and Sheldon fighting? What does Wil Wheaton have to do with all this? Who decided to bring back “Fun With Flags”? (Because we want to thank them!) Could Sheldon really be in danger of losing Amy? And does he really know how to milk an invisible cow?

We’ll find out for certain on Thursday, but in the meantime check out these new photos from “The Habitation Configuration” which shed a few more light-particles on the events of the episode.

CBS’ official description says:

Wolowitz struggles with moving out of his mother’s house. Meanwhile, Sheldon is caught in the middle of an argument between Amy and Wil Wheaton.

The episode will also feature a cameo from former Star Trek-ee and Reading Rainbow host LeVar Burton. Burton has previously popped in briefly on The Big Bang Theory in “The Toast Derivation,” though he did not interact directly with any of the main cast.

The Big Bang Theory should be back next week with “The 43 Peculiarity,” after which the show may be taking a hiatus, though this has not yet been confirmed. Hypable will keep you updated with all news for The Big Bang Theory as it becomes available!
