Oh, you meant EPII by beginning of the war... I think that would work in both ways. Putting it here I think it acts as a reminder of what happened before, and as a way to serve the new scroll. Although I don't know, it could work in AOTC too. Other ideas I had to strenghten ObiWan and Anakin's friendship were chained to the "almost fracture" in the Order (remember the "no" gesture?). If you put a resolution to the idea of serving oor not in AOTC, there's no disagreement within the order by ROTS. I don't know how much of that you're taking for your edit. However, you're always free to take the idea, and draw it with your own hand, or even drawing the part of it that you liked for the most, it's your edit :)
But having you considering putting that line in EPII, I guess that could be interpreted as your official statement that you'll eventually get to AOTC?? :)
