Here are some infos from the ‘Bones’ panel about the Fourth Season.Credit to davidboreanazweb.comFrom Zap2it:- This is the season of gettin’ some. An ex-girlfriend will come into Angela’s life; Cam will have a tryst with one of Angela’s exes (the same girlfriend, maybe?); and Sweets may find love.- And, yes, Bones and Booth will be naked in bed together. That said, she’s seeing both a deep-sea welder and a botanist in the clip shown, so the “will they or won’t they” continues.- We’ll see Booth’s extended family this season, and the Gravedigger (the killer who buried Bones and Hodgins in season two) will return next season.- The diner setting will probably be left behind, as was the original Chinese restaurant hangout. Boreanaz is pushing for someplace where he can get a good Scotch.- Along the same vein, Hanson wants to do a reunion episode featuring secondary characters like Dr. Goodman.- Zack will definitely be back.From EW.com:For those of you none too pleased by the turn the Gormogon case took in the season finale ? and Hanson says he realizes there are many of you ? there is a bright side: Millegan will return as Addy for an unknown number of episodes. Of course, he’ll still be that-guy-who-killed-for-the-cannibal, but…still.There’s also love in the Jeffersonian, with Cam (Taylor) and Sweets (Daley) each getting lucky (no word on whether it’s with each other), and an ex-flame of Angela’s (Conlin) returning. Also: We finally meet Angela’s long lost mystery husband, from whom she’s been trying to get a divorce so that she can marry fellow lab rat Hodgins (T.J. Thyne).The biggest spoiler, however, was Hart revealing that, “This year, Booth (Boreanaz) and Brennan (Deschanel) will be in bed together naked. That’s all I can say about that.” And for those still smarting over the season finale, he offers some consolation in revealing that it wasn’t exactly the way he wanted to end the season either. With the writer’s strike throwing the schedule off, the Bones creative types figured they’d conclude not with the Gormogon killer, but with Booth getting shot. So look at the bright side, Bones
