Brennan's patience and professional judgment will be put to the test in the next episode of 'Bones' season 10, with two members of her team tying the knot.

The fifth episode of Bones showed how Brennan (Emily Deschanel) and Booth (David Boreanaz) tried to solve a murder that involved one of their colleagues, Dr. Jack Hodgins as one of the suspects. This caused distress to the two lead actors. Thankfully, they have found a resolution.

In the next episode of Bones entitled "The Lost Love In The Foreign Land," Brennan experiences another taxing predicament concerning her team.

Two of her teammates, Dr. Saroyan (Tamara Taylor) and Arastoo (Pej Vidat) are planning to marry, and this could affect Brennan's professional judgment. Brennan is to grade Arastoo's dissertation, and their marriage might cause Brennan to doublethink.

Meanwhile, Booth and Brennan will investigate a crime involving an immigrant house helper found at the side of the road.

The main suspect is the victim's employer, which will be played by Phyllis Logan. Logan is famous for appearing in the hit show 'Downton Abbey,' and will guest star in this Bones episode.

"The victim's wealthy former employer, Sandra Zins (guest star Phyllis Logan), is a key suspect in the case, but when the team discovers that the victim might have been brought into the country illegally, the team realizes the case is much bigger than it seemed," said the episode's press release, as reported by SpoilerTV.

Booth and Brennan's investigation will lead them to a deeper and more complicated angle – illegal human trafficking. This would prompt them to re-strategize their investigation.
