Volume 2, Episode 31: Deuce rocks his musical tribute to Cleo, meanwhile, Frankie's in for an electrifying surprise.


After a good time with Holt in the last webisode, Frankie tries to convince herself to break up with Jackson, but then she sees him in the hallway and is reminded of the fun she had with him. Frankie's imagination runs wild when she creates to smaller versions of the boys she likes, who fight over her love. Before going to the restroom, Frankie said that she needs to clear her mind.

Cleo de Nile is trying to find Deuce Gorgon so she can break up with him. After the dialogue between Cleo de Nile and Deuce Gorgon, the relationship between them was almost over, when Operetta and Memphis "Daddy O" Longlegs save the relationship by stopping Cleo so she can hear the song Deuce made for her. When Cleo finally understood what was going on, she was touched by Deuce's song and apologizes to him and Operetta.

Frankie and Jackson walk into the same hallway Cleo was in, but then after hearing the music, Jackson transforms into Holt, and Frankie was shocked with what she saw.

  • The title is a play on the phrase "Here Comes Trouble." "Treble", meanwhile, is a musical term, but can probably also refer to the word 'treble' meaning "triplet" as in three sets, the truth about Operetta was leaked and so was the singular truth about Jackson and Holt.
  • While Frankie tries to decide on who to pick out of Jackson and Holt, small caricatures of them appear akin to cartoon or comic symbolisms of the conscious's split into two small entities, one an angel and the other a devil, on a person's shoulders.


  • Gil returns to Monster High after having been enrolled elsewhere prior to "Back-to-Ghoul" by his parents out of anger that he's dating Lagoona, a salt-water monster. He will explain the circumstances of his return in "Fright On!".
  • It is finally discovered that Jackson and Holt are the same guy.
