Bones Season 8 finale airs Monday (Apr. 29) on Fox in the U.S. Evil tech genius Christopher Pelant is back and he is going after FBI Agent Seeley Booth. Temperance Brennan will have a worse nightmare this time around. Does the situation push her to rethink her beliefs about marriage? Bones producer Stephen Nathan tells fans, "Keep some Kleenex nearby."

Bones Season 8 finale is called "The Secret in the Siege." TV.com has a very brief teaser about this episode: "Pelant has returned to play more mind games with the Jeffersonian team and has made Booth his new target."

What fans could draw from that synopsis is the whole Jeffersonian team will be involved again, but perhaps this time as a target. In the Season 7 finale, Pelant almost had Brennan jailed. This time, he is going after the most important person in Brennan's life. This is nightmare a hundred times over for Brennan.

In an interview with TVFanatic.com, Bones producer Stephen Nathan said Pelant's comeback "has the biggest impact on Brennan." The Jeffersonian team has just gone through a life-threatening ordeal in the Season 8 penultimate episode. Mortality was an ever-present character in the lab, but even more so when one of them is in a life-threatening situation.

"The past three episodes have affected [Temperance] probably more than anyone. She's looking at life in a very different way now. I think this surprises her most of all. She is really going to be looking at herself, her own life, the choices that she's made and how she wants to see her life in the future in a very, very different way," Nathan said. This connects well to other spoilers and teasers saying Brennan and Booth will be bringing marriage talks back to the table. At least fans know that something potentially good is brewing despite Pelant's return.

However, in a separate interview with TV Line, Nathan said, "I'm not going to divulge whether [some wedding plan] moves forward or not." (Fair enough, Mr Nathan.)

Will Bones Season 8 finale spark some waterworks among avid fans of Brennan and Booth? Nathan told TVFanatic, "I would just say for those who have a penchant for tears, keep some Kleenex nearby."
