In the "Prayer for Mad Sweeney" episode, the car accident throws Laura through the window and rips the golden coin from her body.
Mad Sweeney picks it up and he is ready to walk away from the dead Laura's body, but then he changes his mind - he screams something in Gaelic (I believe that at least...) to the surrounding forest, and after placing a few missing bits back into Laura's chest, he gives her back his special coin.
What was he saying?
Bonus question: What fell off from Laura's body?
