"Hawaii Five-0" season 5, episode 4 spoilers reveal that Chin will join Danny for the release of his brother Matt Williams. The team will also find surprising motives when it investigates the murder of a hired killer.

The "Hawaii Five-0" season 5, episode 4 spoilers are revealed through the synopsis which reads:

"When a Detroit hit man is taken out by one of his colleagues on the streets of Oahu, Five-0 is shocked to learn the killer's surprising motives. Meanwhile, Chin puts his career on the line to help Danny get the money he needs to save his bother's life."

The next episode is titled "Ka No'eau" and Cartermatt said that the mystery of Danny's brother Matt will continue.

"Even though this is the fourth episode of the season coming up, there is still no concrete word on when or if Dane Cook is actually going to show up on the show," it said.

Matt was abducted by Marco Reyes after Danny's brother went on a run way back in pilot season. The kidnapping has something to do with the $18 million that Matt allegedly stole.

At first, Danny didn't really believe that Marco Reyes has his brother but all doubts have been erased by the end of last episode, the police officer was finally resigned to the fact that his brother was indeed being held hostage.

Danny was also able to find the buried money through the cules left behind by his brother.

Meanwhile, more "Hawaii Five-0" season 5 spoilers can be gleaned from the article by Primetime Unreality TV, which claimed that McGarrett will meet a woman who helps him resolve a case that his father has been working on before he died.

Previous reports claim that McGarrett would meet a woman in a future episode although it's not clear if they are going to be romantically involved, or if he moves on from Catherine.
