Episode 5.01: The Harbingers in the Fountain (Season premiere)
07/24 - Series creator Hart Hanson confirms that a season-opening smooch "was scripted," but adds, "I'm in no way confirming that it was a sincere scripting. Could have been a way to identify leaks."
07/12 - Twelve human skeletons were found beneath a fountain and all of them were poisoned and at least one of them was murdered with a speargun because the poisoned didn't work on that victim. Their ingestigation brings them to the Harbingers of a New Day, which seems to be a sort of religious group or cult that wants to live in a underwater utopia. Booth wants proof that one of his suspects was actually named differently in the past. As hinted in the spoilers below from Korbi TV, Booth and Brennan will indeed share a kiss after he rescues her from a dangerous situation. It looks like Cyndi Lauper's character may be named Avalon Harmonia and would be introduced in this episode. Caroline, Angela, and Sweets also appear.
07/10 - Apparently, when Booth asked Brennan who she was in May's finale, he didn't mean to imply that he didn't remember her. Apparently Booth just wasn't sure whether she was his partner, Bones, or his wife/baby mama from the hallucination/alternate reality he experienced while drugged up. Because of his confusion, we're hearing Booth will continue to struggle with romantic feelings for the good Dr. B throughout the season premiere and may even kiss her after rescuing her from a dangerous situation.
06/14 -"Booth's problem isn't remembering who Brennan is," [Hart Hanson] tells me, "it's remembering which Brennan she is. " Source: The Ausiello Files
04/05 - '80s pop icon Cyndi Lauper is in talks to recur next season as a kooky psychic that Booth and Brennan bring on as a consultant.
