Lyrics:
Verse 1
On bright screens we chase a trail of scars,
Tiny barcodes lighting up who we are,
Family lines through a crowded storm,
Every split a story taking form.
Pre-Chorus
Not guesswork, not a single clean line,
We let the maybes breathe in time,
Hold the doubt right in our hands,
Watch it turn to shifting plans.
Chorus
Draw the map of the leaving, let it speak,
From the first seed to the places it will reach,
Not one road—there are rivers in the dark,
And we measure every question with a spark.
Draw the map of the leaving, feel it move,
Routes and timing, and the edges we can’t prove.
Verse 2
Two clocks ticking—mutation and the run,
Different rhythms, but they fold into one,
A tree grows tall with a hidden bend,
Where a side door opens, where the branches end.
Bridge
Sometimes signals fade, the trail runs thin,
Too few marks to know where we’ve been,
Still we learn what the data won’t allow,
How far we can see, and how to see it now.
Final Chorus
Draw the map of the leaving, let it speak,
From the first seed to the places it will reach,
Metastasis to metastasis, back again,
A looping truth written under the skin.
Draw the map of the leaving, stay awake,
Every uncertain edge is a promise we can make.
