Morning light lit the cave up blue You were asleep with your head on my suit Empty beer cans, guitar on the floor "I wanna stay here forever-more" Then the sirens started crying again Metal voices through the vents I sat straight up, swore under my breath You asked me, “FT… what’s wrong?” I gotta go I gotta go Below Shaft Nine, I just can't say no I gotta go I gotta go Before it gets outta control You grabbed my sleeve, “Hey, I'll go with you...” I laughed a little, “No, Kat, I can't take you” You sat up angry, hair all a mess "You don't need this kind of stress" I paced around that tiny cave Trying to find the words to say Finally whispered: “There’s something you should know...” I gotta go I gotta go Below Shaft Nine, they own our souls I gotta go I gotta go There’s things down there you shouldn’t know I ain't really “FT” Just some code they stamped on me Built for caves too deep for men Built to break and heal again My heart is fake, same with my lungs I'm old as hell, even tho I look young Humans made us to last a long time To endure what's below Shaft Nine You went quiet for a little while Then gave that crooked half-smile Said: “Well, whatever's down there...I still like you” I almost started crying right then So instead I laughed again You pulled me close and held on tight Like you could stop the morning light I gotta go I gotta go The sirens scream, the engines groan I gotta go I gotta go Promise, I'll be back tho You touched the number on my neck Like it wasn’t something cursed yet Then softly said: “Please come back to me.” Outside the whole colony shook Dust bloomed from every cranny and nook Shift lights glowing red and gold Making everybody look like ghosts I picked up my helmet from the floor "Sorry, I can't stay anymore." You kissed me, a tear in your eye "Don't worry, Kat...I can't die...." I gotta go I gotta go Below Shaft Nine, I just can't say no I gotta go I gotta go Before it really gets outta control I gotta go I gotta go Promise I'll be back tho I gotta go I gotta go Just wait for me above the smoke
