Underground Sound - Lucha Underground recap for August 30, 2017

Dario Cueto talks to his brother, Matanza Cueto. He says he was wrong, and that he thought he knew best but did not. He kept him locked away because he thought he was obsessed with Rey Mysterio Jr., but now he understands that Matanza wanted to protect him, and thanks to him, he did not get hurt. He talks about how Rey gave him a 619 and humiliated him, and says that Rey must pay. He tells him to be patient for two more weeks, for it is then that he will get Rey one-on-one. When that happens, Dario wants Matanza to destroy him. Matanza grabs the bars and shakes them in a fit of rage.

It is announced that Ultima Lucha Tres will be four nights long, and that Johnny Mundo will defend the Lucha Underground Championship against Prince Puma.

Son of Madness beats Mascarita Sagrada, then Son of Havoc attacks him after the match. Dario Cueto calls out security to separate both men while Paul London helps Mascarita Sagrada to the back. Cueto then makes a match between Havoc and Madness for one of the seven Aztec Medallions, and since they are both motorcycle gang members, it will be a Boyle Heights Biker Brawl.

Marty "The Moth" Martinez not only beats absolutely decimates Argenis - who is in his first match to the point that he busts him open and removes his mask after ripping it open from the front. Argenis has to cover his head with a towel as he is tended to by a trainer. Mariposa then takes the microphone from ring announcer Melissa Santos, whom asks Melissa if he liked what she just saw before saying he wants to rip Fenix's mask off at Ultima Lucha Tres and show the world how ugly Fenix really is. Fenix then shows up from behind and drop kicks Marty before superkicking Mariposa. Melissa says that she doesn't think Marty can't take Fenix's mask, and Fenix ups the stakes by demanding it be a Mask vs. Hair Match.

Joey Ryan beats Sexy Star. During the match, Taya shows up with a sign saying "Go Sexy Star!" in an attempt to distract Sexy Star. It works, but not as expected: Sexy Star superkicks her before putting the sign through her head. When she gets back in the ring, Joey Ryan superkicks her for the win. After the match, Cortez Castro attacks Joey Ryan from behind with a Kendo stick, and Joey Ryan eventually runs to the back.

Dario Cueto is in his office when Cortez Castro shows up. Cueto says that Castro has impressed him, and knows he is here because he is a cop. Castro wants to arrest him for what he did for Mr. Cisco. Cueto threatens to hit him with the red ceramic bull on his desk, but stops himself halfway. Cueto says he loved what he did to Joey Ryan, whom he knows is also a cop. He books him for a "5-0 Street Fight" against Joey Ryan next week. Cortez Castro says that he does not work for him, and Cueto agrees, but he knows Castro likes to fight and that he hates Joey Ryan, and he cannot fake that. Castro says he will see him next week, then breaks the Kendo stick over his knee and leaves.

Son of Havoc beats Son of Madness in a Boyle Heights Biker Brawl to earn one of the seven Aztec Medallions and take his colors back.
