Miko had insisted Earth had more than one langue. He was unsure of that claim, everyone on Cybertron spoke the same thing. So she showed him Vocaloid and J-pop. Breakdown wanted to curse the human girl to high hell.

Breakdown: please..for all that I love you…
Knockout: yes, dear?
Breakdown: just..no…never again
Knockout: never what again?
Breakdown: I'm sure that..uh..music..has a place..just not..out of your mouth
Knockout: why not?
Breakdown: you sound like a girl on crack

Knockout looked shocked at Breakdown and then hurt. Breakdown winced, he hadn't meant to be so crude and reached for the red mech. Knockout deiced to let him, despite how much his words had hurt.

Breakdown: I love you, Knockout, but you should find songs that show off your talents…and not songs that make people question your gender or makes Megatron want to take your voice box out..
Knockout: but…I like miku….she's cool…
Breakdown: never again do I ever want to hear you sing miku…
Knockout: kill joy…
