The Passenger lyrics

I didn't know you were there
Until you said "hello."
You had been watching me
For I don't know how long.
I hit my head against the lamp,
As by surprise I stood up.
"Don't be afraid," you said,
"it's only me- The door wasn't locked."

The voice I'd heard in the hall
Was hard to recognise.
But now we know he's onboard,
Wearing our disguise.
If only you and I could trust
Each other through this,
Then together we could
Work out who the enemy is.
