I performed this spell and something that did not cross my mind previously. As far as contacting the target, if they contact you for something on friendly terms does this get the IS to stop his/her work on the target? Not exactly the return that I desired, but since we are on friendly terms I should have expected this. Should I recast or will the IS know that he is not returning to me with my desired result?
My take on this, you may be starting to feel guilty that you tried to use the spell on a friend and are then making it not work. If you doubt it or feel you did something wrong, a spell won't work well. You can re cast or you can accept the friendship. I wouldn't cast that spell on someone I was on good terms with, but I'm not a kid so things are different today.
