As part of his "services," Duclair then somehow tracks down Anthony Brent, a two-time convicted arsonist who he determines was the responsible party, and roasts him alive in a controlled fire (we do not see Duclair doing this, only the results).
Now that he is free, Duclair isn't happy to just knock off Brent.
Then Danno, Grover and Rey hook cables dangling from the copter under the cabin which Mc Garrett then lifts up with the three of them inside and takes them to safety (seriously).
Duclair fled into the burning forest some time before this, and he is the only casualty of the blaze, according to news reports.
The fate of both of their characters was explained.
The episode began with an "out of nowhere" moment with Mc Garrett and Danno showing up at the Hilton Hawaiian Village where the racially-ambiguous (for Hawaii) Tani Rey (Meaghan Rath) is working as a lifeguard at the Paradise Pool.
