One more Lawrence brother and “Hawaii Five-0” will hit a ’90s trifecta.

Already home to Andrew Lawrence, the CBS drama will tap the actor’s elder brother as a guest star for season 8. Far from cementing their familial bonds on screen, the pair will find themselves on opposite sides as Joey Lawrence lands at No. 1 on Five-0’s most wanted list.

‘Hawaii Five-0’ throws back to an old villain

Does the name Ian Wright ring a bell? It should, particularly as the hacker met a bloody end at the hands of Wo Fat and was portrayed with a frightening level of malice courtesy of the affable Nick Jonas.

Now, years later, Ian’s brother will arrive on Oahu to continue his legacy.

“Lawrence will appear in two episodes in the upcoming eighth season, playing Aaron Wright, the brother of world-class hacker Ian Wright, who Five-0 encounters when he uses his computer to free a dangerous arsonist from prison,” Variety announced on Tuesday.

It’s unknown when Aaron will make his debut, although filming is currently underway for Joey Lawrence’s first episode. The actor tweeted a set photo of himself and his brother Andrew (Eric) near the end of July.

“Something's cooking on the #island,” Lawrence teased. “Stay tuned.”

Now we're left to wonder if “cooking” is a cheeky reference to the arsonist storyline or merely a fortuitous turn of phrase.

Duclaire, “Hawaii Five-0”’s most infamous firebug, is already six-feet under. Will the series introduce a new sparky, or is there another fiery Five-0 nemesis sitting in Halawa? Viewers will just have to wait and see.

'Hawaii Five-0' controversy

Aaron will hardly be the only new character to rub shoulders with McGarrett (Alex O’Loughlin) and co.

this fall. Grace Park (Kono) and Daniel Dae Kim (Chin), both members of the OG task force, departed the series ahead of filming for season 8. Their exit was prompted by the network’s refusal to equalize their pay with that of their fellow white castmates, a decision that has riled fans and actors alike.

Speaking at the Television Critics Association’s summer press tour on Tuesday, CBS Entertainment president Kelly Kahl attempted to write off the shakeup as merely an unavoidable side effect of a long-running series.

“In my mind, it was purely a business transaction,” Kahl said, as per Variety. “It’s happened on ‘CSI,’ it’s happened on ‘Grey’s Anatomy,’ it’s happened on ‘Law and Order: SVU.'”

No matter CBS’ attempt to gloss over Hollywood’s notorious issues of inequality, Park and Kim’s exit means someone will have to fill their shoes. For this reason, “Hawaii Five-0” will welcome Meaghan Rath as failed police academy cadet Tani Rey and Beulah Koale as former Navy SEAL Junior Reigns.
