'Hawaii Five-O' Season 6 News, Spoilers: What to Expect in "Lehu a Lehu"

After the explosive and emotionally intense premiere showing for the sixth season of CBS' hit police-procedural drama TV series "Hawaii Five-O" comes yet another action-packed development as the show moves on this week for its second episode.

Titled "Lehu a Lehu" ("Ashes to Ashes"), the synopsis from TVGuide said that after the attack on a bomb squad, a perpetrator threatens to detonate more explosives planted in some of the most populated places in the city unless his demand to see an arsonist, Jason Sinclair, released from prison be met.

The team will realize how dangerous Sinclair is and the extent of what he can do by merely tugging some strings in his deep network of connections. Will they be able to manage the crisis while at the same time ensure that Sinclair won't be free to roam?

Aside from the bomb scare situation, the episode will also feature the aftermath of the events that ended up with Kono missing some teeth and Adam getting shot. Both will take notice that they are being watched.

As for McGarrett, the summary suggests that fans should be in the lookout for his plans to take his relationship with Catherine to the next level.

Earlier this month, it has been hinted that the squad leader might be asking Catherine to tie the knot. Executive producer Peter Lenkov told Entertainment Weekly that McGarrett is now "ready to take that major leap in their relationship" which he considers as "one of the bravest things this soldier has ever done."

But this affair is not expected to happen in a straight line. Lenkov said, this time in an interview with The Hollywood Reporter, that there's still some commitment issues that they need to clarify between themselves.

For those who missed it, Catherine left Steve to continue her search mission in Afghanistan.

Other than that, the showrunner also pointed out the arrival of Sarah Carter as Lynn, "a nature lover with whom McGarrett goes on a wild adventure."
