Bishop (Emily Wickersham) and Quinn (Jennifer Esposito) will go to Philadelphia in the upcoming episode 5, titled "Philly," of the 14^th season of the American crime procedural drama "NCIS."

Gibbs (Mark Harmon) decides to send Bishop and Quinn to Philadelphia to work with MI6 officer Clayton Reeves (Duane Henry). This is after they find out that a missing MI6 Officer has something to do with the murdered petty officer. Quinn, on the other hand, shared the painful time when an NCIS case pushed her to leave field work. Also, former NFL player Tony Gonzalez is expected to guest star as Special Agent Tony Francis.

The promo trailer for "Philly" shows the agents being forced to work on the edge as they investigate the case on the missing MI6 Officer. While Bishop and Quinn team up, it seems like there is tension between Quinn and Gibbs as she struggles to pour her best in the field work. Meanwhile, Nick (Wilmer Valderrama) team up with Timothy (Sean Murray) for another case and things will become very action-packed for the two.

In other news, according to Entertainment Weekly, a November episode will explore on Ellie (Emily Wickersham) and how she gets to learn more about the issues between her brothers. Apparently, the said upcoming episode will be a Thanksgiving special. It will be introducing two brothers John (Jesse Bradford) and Robert (Jesse Johnson). John is the fun and protective of the siblings, while Robert is intelligent yet drug dependent.

Both John and Robert will visit their sister Ellie for Thanksgiving. However, they become very protective of her when they suspect that she is dating someone. Their third brother, George (Ryan Doom), will also appear in the episode as well. Despite Ellie's excellence in her job as an agent, the brothers will still step up to protect her.
