We have an adventure together

I hatch a disheveled plan,
with my twin inside my hand
Wisps whisper and portend our scheme
we will never be redeemed

Red juice, bitter and briney
Transpire from my foolish soul
White osseins, shardy and sharp
from my arm they point crosswise

You are dumb and you proved that!
Twin, yield me from flattery
It's night, the sun fondles my chest
Forgive me, we are both dead
