In his latest spoiler-riffic column, Michael Ausiello reveals a couple Bones tidbits regarding the rest of the season.

Which recurring character will return? How will the season finale play out? Answers and teases are below:

• Billy Gibbons (pictured, of ZZ Top) will reprise his role as Angela's father this spring. Says Michaela Conlin: "[He] comes back on the show in a really killer way... I should clarify that. It’s not in a Bones killer way, but killer as in cool ass. He has a really great episode."
• As for the May finale, producer Stephen Nathan describes the episode as “the next logical emotional step after what happened in the 100th.”

What happened, of course, was that Brennan crushed the hopes and dreams of Booth, not to mention viewers around the country.

So, what might this "step" entail? We'll have to tune in and find out.
