Sorry, me again so quick. I was sure I could find my second fic under time travel, but apparently it wasn't there.

I am looking for a story where Gordon Walker travels through time to kill Dean and Sam when they were little so they won't excist in his time line. The boys follow, but something strange happened.
Instead of arriving there in grownup forms, they are placed in the bodies of when they were children. Gordon about 8 years old I think, Dean 5 and Sam 2..not sure about the correct ages. i do remember that Sam had trouble walking, so maybe he was 1 instead of 2?

I hope someone recognizes the fic and can tell me the link?

Thanks in advance.
