A good story I do love time travel fix it stories. In this case I found this some time ago I just forgot about it. Stiles decides he needs to do things right and working with his magic for several decades manages to make a spell to send him back. He plans to makes sure that he is the one bitten and not Scott. He is determined to save everyone and end up with the one he loves. Of course things don’t always go his way especially making meals for someone and using their own recipes that they have never shared, oops. He is determined to get his happy eve-rafter.  The story is funny and I love sane Peter and poor innocent Derek.
