'Bones' Season 10 Spoilers: Will David Boreanaz, Emily Deschanel Deliver Lance Sweets' Son? [WATCH]

When Bones made its season 10 premiere on FOX, the episode kickstarted with the unexpected death of Lance Sweets (John Francis Daley). With his pregnant widow left behind, will Booth (David Boreanaz) and Brennan (Emily Deschanel) pull through for their fallen friend and deliver Sweets' son?

We saw how devastated Booth (Boreanaz) became over his friend's death. In the tenth season premiere, Sweets (Daley) was caught in the crossfire after trying to clear Booth's name for murder. In the aftermath, Booth and Brennan's adorable daughter, Christine, was dressed and ready for "Uncle Sweets" to take her to the park. Blaming himself for his friends' death, Booth was so heartbroken as he watched Brennan explain to their innocent child about death.

As we previously mentioned, Sweets' funeral was a way for the cast to say goodbye and introduce themselves to FBI Agent James Aubrey (John Boyd), Sweets' successor. Just because Aubrey wants to help the team, that doesn't mean Booth will accept it at first. As Aubrey and Booth come to terms about being partners, there is still the matter of Daisy (Carla Gallo) and Sweets' unborn son to deal with.

TV Line reports Mindy Cohn (Facts of Life) will guest-star as Valentina, Daisy's New Age coach. Bringing in levity and lightheartedness, Valentina wants Daisy's childbirth to be a peaceful process filled with spiritual energy. Cohn will appear in an early December episode entitled The Puzzler In The Pit.

In the Geek in the Guck, Sweets' previous ex Jessica (Laura Spencer), will resurface in tonight's episode.

Check out this sneak preview of Geek in the Guck here. In the scene, Booth and Brennan have a hilarious conversation about sending their child to the right kindergarten:
