'Hawaii Five-0' season 7 episode 10 spoilers: Danny's sister visits; Masi Oka exits show in episode 13

Danny's (Scott Caan) previously unnamed sister will now have a face and a name when "Hawaii Five-0" airs a new episode in two weeks. Will she prove to be a burden or a welcome surprise to her brother?

Bridget (Missy Peregrym) comes to Oahu for a business conference, and perhaps some quality bonding time with her brother as teased in the promotional images for the episode. Bridget seems like a fun and friendly person but Danny will soon come to suspect that she's getting inappropriately close to one of his co-workers.

Could this co-worker be his partner Steve (Alex O'Loughlin), whom he is seen introducing to his sister in the images? Will she be showing interest beyond friendship, or is Danny just making mountains out of molehills like he is wont to do?

When TV Line announced Peregrym's upcoming guest appearance in CBS' long-running police procedural series, she was described as a corporate woman who lived in New Jersey with her husband and kids, and who always seemed to have everything under control. Danny has been used to seeing Bridget in professional settings, but her visit to Oahu will be showing him a side of her that he doesn't know.

What will Danny find out about his sister? Will it turn out to be something good that brings them closer together, or something bad that pushes them further apart? Is Bridget having problems at home with her family, or is she in Hawaii purely by chance?

The episode titled "Ka Luhi" ("The Burden") will also bring a 10-year-old cold case involving a missing teenage girl to the Five-0's itinerary when a boy with post-traumatic stress disorder realizes he may have witnessed the girl's murder after he underwent hypnosis treatment.

"Hawaii Five-0" season 7 returns on Friday, Dec. 9, at 9 p.m. EST on CBS.

Meanwhile, Entertainment Weekly's exclusive interview with actor Masi Oka revealed that his character Dr. Bergman, who is Five-0's chief medical examiner, will be exiting the show in the upcoming 13th episode. He will be moving to Africa with his wife, Sabrina (Rumer Willis).

Oka shared that since a majority of his work has been based in Los Angeles and Japan, commuting to Hawaii to shoot for the show has become increasingly difficult so he and the producers mutually decided to let him take a reprieve from the show.

"It's going to be a greatest hits, so you're going to see things that really made Max's character very interesting and unique," said Oka when described his sendoff episode.
