Thanks to TV Guide, we’ve got some info on Navi’s guest spot on Castle.

Rawat will trade in her math textbooks to play Rachel Walters, a mummification expert who crosses paths with Beckett (Stana Katic) and Castle (Nathan Fillion) when the Natural History Museum’s assistant curator, Will Medina, is found murdered. Rachel informs the team that Will might have been cursed because he disturbed ancient Mayan tombs to create the museum’s newest exhibit.

Rachel, who could be a suspect in the murder, also catches Castle nosing through some coffins in the museum, prompting Becket to tease Castle about the curse. Castle refuses to believe her until he suffers his own near-death experience.

The episode, entitled “Wrapped Up in Death,” is slated to air April 5.

2nd to last episode of the season, and some amazing scenes, as Charlie gets a chance to teach abroad and they plan a future. As a treat, I did the caps in HD and kind of went a little cap crazy, so have fun.

A little treat for the Navi Rawat gallery, we’ve got HQ copies of the stills CBS has releases for episode 6×16 “Cause and Effect.”

My apologies for how long it took me to add these, but last week’s screencaps of Numb3rs are up–and such a good Amita episode.

Remember to also tune in tonight to an all new Numb3rs.

Some of the cast has been “tweeting” from the set of Numb3rs, and Alimi Ballard has put up some AWESOME photos of Navi from the last episode of the season. I’m just linking to the album, as its spoilerish.
