First we have "farm boy" Anakin. This version would be used occasionally for flashbacks to his life before entering the Jedi order. I also wanted to make sure one part of the story involved Anakin and Obi-Wan in a really bad situation and use a flashback of each of them talking to Qui-Gon during the time of Episode I to help them get out of the predicament.
This young Jedi version would be used in a flashback to show Yoda training Anakin with other young-lings. As well as one of the first times Obi-Wan takes Anakin on a mission. I thought it could give him good depth to show how he acts around other young-lings.
