Soooooo.... You asked a favor of the devil, and instead of agreeing to a payment, you let him trick you into leaving it as a favor.... Now you owe him, and it may end up costing you something you didn't even know was yours to give....

I'm talking of course about your ex.... He may work for the devil but YOU are the one he really pledged his heart and soul too.... The devil confirmed that without either of you realizing it when he "had to check" and he's a jealous "man"

Words of advice (even though I know you won't listen) do not go after your brother, and look into ways a section of land can be changed, and into what it can be changed....
