Hawaii Five-0 has cast Missy Peregrym as Danny's sister and she will reportedly make her first appearance in Season 7 episode 10.

Peregrym will be essaying the role of Bridget, and according to TVLine, she will be coming to Hawaii for a corporate retreat. Bridget lives in New Jersey with her husband and children, and during her time in Hawaii, she will bond with her brother. It is also being reported that Scott Caan's Danny will witness a new side to his sister after seeing her in a professional setting.

A TVLine reader seems to have caught a bit of Hawaii Five-0 Season 7 episode 10 filming last week. "I saw her filming at the Hilton Hawaiian Village one week ago with Scott. Had no idea who she was. Still don't. The scene we saw was at a bar and they share a hug after a short chat," the reader noted.

Hawaii Five-0 is aired on Fridays on CBS. The next episode is titled Ke Kū 'Ana and the official synopsis reads: "When a cache of guns is stolen from a gun range, Five-0 discovers the culprit is intent on making a dramatic and potentially deadly statement on gun violence. Also, Kono and Adam are finally reunited when he is released from prison."

The mystery of the chess piece killer was solved in the previous episode, with McGarrett and Alicia finding out that Madison was behind the killing spree. However, before they could nab her she fled, but not before trying to kill Alicia and McGarrett. This storyline will pick up sometime later this season.
