"No a wish you made in a fit of anger, when you mistakenly thought mom was cheating on you, accidentally changed your future. You where left unable to fix it, and I was shielded by a gift aunt Zoƫ gave me" Greg showed Jon his pendent
"So we just need to make a wish right? I get it you came back so you could make a wish that proceeded and negated my hasty wish and thus would negate my wish, Right?" Jon asked.
"No dad as you, the future you told me Time is nothing to the stone" Greg said
"Ok so what do you plan to do? And why know"
"First I'm 17 and in my time you're 35, I have one week to get you and mom to hook up so to speak"
"But how with it fix your time the wish I will make" Jon asked
"A wish can't undo another wish, but if you can cause an event to happen that a future wish tried to undo you negate the wish, but after I fix this I'm gonna have to stop my dad from making the wish"
"So you basically have to help me loose my virginity in the next week, who's your mom anyway"
