Cam's (Tamara Taylor) wedding preparations will hit a snag when her sister arrives in town in an upcoming episode of "Bones."

In the episode titled "The Stiff in the Cliff" that's expected to air on June 23, TV Guide reports that the other Saroyan sister, Felicia (Rochelle Aytes), will visit Cam to help with the wedding plans. The Jeffersonian coroner is getting married to Arastoo (Pej Vahdat) soon and there are lots of things to prepare. Felicia's presence is meant to lighten the burden for the bride, but as loyal followers of the series know, they do not exactly share a good relationship.

Felicia is younger than Cam, but she is as competitive as her sister. Because of their clashing personalities, they do not see eye to eye on many things. Felicia is bound to tell Cam exactly what she thinks, from the bridal gown to the outfits of the bridesmaids. Since she is already stressed out with all the preparations, Cam is sure to tell her sister to keep her opinion to herself. Will they eventually reach a compromise, just like siblings do?

Meanwhile, in the same episode, a new dead body will be brought to the Jeffersonian for examination. The synopsis reveals that the remains of an explorer will be discovered after ten years of his disappearance. The rich man was a part of an expedition in Antarctica when he suddenly went missing. The team will be surprised to learn that one of the suspects is one of their own, Dr. Clark Edison (Eugene Byrd). He was one of explorers with the victim a decade ago.

In the meantime, CarterMatt reports that the June 16 episode titled "The Head in the Abutment" will see Booth (David Boreanaz) back in the ice hockey rink as he faces an old nemesis. Hodgins (T.J. Thyne) will also battle it out with an intern on who between them can bring back a human head from the bottom of river via the drones he constructed. Who will win?

"Bones" season 11 airs Thursdays at 8 p.m. EST on FOX.
