Treacherous

“All we are is skin and bone Trained to get along”

Skin and bone is what is left of a body that has been worn down, and the line that follows makes the wearing deliberate. The damage here is not an injury but an attrition, the slow reduction of two people to the minimum required to keep the peace.

“Your name has echoed through my mind and I just think you should, think you should know”

The name-as-echo figure lands here in its purest catalogue form, the partner's name returning through the speaker's mind on its own initiative, and the returning itself becoming the evidence the speaker offers him of how deeply the encounter has landed. The line sits inside the song's confession structure, with the echo as the unbidden interior phenomenon the speaker thinks the other should know about. The acoustic figure carries the song's whole argument: the reverberation proves the original sound was felt.

“Out of focus, eye to eye 'Til the gravity's too much”

Proximity is what destroys the focus, so the closer the two get the less either can be seen. The blurring is a consequence of intimacy rather than of distance.

“I'll do anything you say if you say it with your hands”

Hands-as-speech register, the canonical description's "hand as the body's most articulate non-verbal site" rendered explicit; the partner is asked to speak through touch, the gesture made the substitute for the word.

“Nothing safe is worth the drive”

Idiomatic 'worth the drive' as the relationship-pursuit register. The line concedes the dangerous attraction by framing it as a journey the speaker has decided to take; the road is implicit in the verb, with the analytical pull sitting on how long the trip is and what she will have to pass through to reach the destination.
