Last week on "Hawaii Five-0," Steve was reunited with his Aunt Deb when she returned to Oahu to spread the ashes of her husband, Leonard.

The McGarrett family had an impromptu reunion of sorts when Mary and Joan also came to Oahu, and Steve learned that the other reason why Aunt Deb was there was because she wanted his help to accomplish a few things on her and Leonard's bucket list.

One of the things on the list involved driving a police car, and Steve indulged his Aunt by handing his keys over to her. What followed was a wild ride throughout Oahu, and later in the episode, Deb discovered that her cancer had gotten worse. She died just as Steve went to wake her up for breakfast, and at the end of the episode Steve and Mary took Deb's ashes with them as they climbed a mountain because it was the last thing on her bucket list.

This week will be all about Grover, Kono, and Chin as the episode titled "Umia Ka Hanu" sees Grover confronting his wife's murderer while Kono and Chin are held at gunpoint.

There have been very few episodes regarding Grover in the past seasons of the show, as the most memorable Grover storyline so far involved the kidnapping of his daughter, Samantha back in season 4. But next week, he will have the chance to get some answers about his wife's murder as according to the official synopsis of the episode, Grover travels to Chicago to get a confession from Clay Maxwell about killing his wife.

Meanwhile, Chin and Kono will be in danger as the two are held at gunpoint by two killers who have no idea that they are cops. It will be interesting how Chin and Kono will try to get themselves out of this sticky situation, as the two have always worked well together in past cases.

"Hawaii Five-0" airs Fridays at 9 p.m. on CBS.
