Even Prof. Dumbledore was mildly suprised when Harry related the sequence of individuals emminating from the wand. I believe that when that person arrived, Lily and James were already dead. That person witnessed the attempted assination of Harry and the results. I believe Wormtail was so scared he fled. He did not transform into a rat, this was done by someone else at a later date. After that night, Sirius tracked him down and got into a lot of trouble. For 13 years, he was in rat form and could not return. If he had transformed himself, he would have able to return. I believe this second DE saw the devastation, reflected upon the events and change his outlook on life. He wrapped Harry in the invisability cloak and sought medical help. He could not go to St. Mungo, it was not safe. I think he fled to Hogwarts with Harry. This is reinforced by the presence of AD, MM and Hagrid at the delivery of Harry to the Dursleys. This individual forever gainned the confidence Dumbledore. I believe this individual was Snape.
