Photos from Thursday night’s episode of The Big Bang Theory have surfaced online, giving us a peek at unexpected handshakes and what looks like more than one uncomfortable conversation. Minor spoilers ahead.

A set of new stills have been released from “The Spoiler Alert Segmentation,” which will air tomorrow night on CBS. The photos focus on a few specific scenes, including at least one multiplayer hallway confrontation. (It’s been too long since we’ve had one of those on The Big Bang Theory!) Check out the photos right here:

In addition to the quadrangular Leonard/Sheldon/Penny/Amy drama (well… “drama” might not be quiet the right word for it!) we also get a glimpse of Howard and Raj’s plotline. CBS hints at the upcoming Wolowitz follies in the official summary for “The Spoiler Alert Segmentation”:

When Sheldon and Leonard fight, it affects Penny and Amy’s living arrangements. Meanwhile, Raj takes care of Mrs. Wolowitz while Howard is away.

Yikes – is Raj even going to be able to open his mouth around Howard’s mom? Will she let him get a word in edgewise, even if he does?

And next week, The Big Bang Theory will be back with a Valentine’s Day-themed episode, “The Tangible Affection Proof.” Rumor has it that this episode is set to be a game-changer for the girls and guys of our geeky gang. CBS says:

While the guys try to give their significant others the perfect Valentine’s Day, Raj and Stuart throw a “lonely people” party at the comic book store.

What are your suspicions for ‘The Spoiler Alert Segmentation’?
