Will tonight's much-anticipated episode of Bones mark a turning point for B-squared?

Directed by series star David Boreanaz, "The Blackout in the Blizzard" features just that ... with Booth and Brennan stuck in the elevator in his building throughout.

One big problem with being trapped in a steel cage? It puts a real crimp in their inability to stop a killer from spreading a potentially lethal virus across the D.C. area.

But their issues don't end there ...

Wearing a thoroughly awesome hat, Sweets checks in on his colleagues periodically, and eventually takes the opportunity to bring up a serious and sore subject.

It begins with H, we'll leave it at that. But where will the discussion end?

“They sort of talk about each other’s feelings for one another,” says cast member John Francis Daley. “Sweets, obviously, loves to see that chemistry. [He pushes them] in a very intrusive, annoying way. The only way Sweets knows how.”
