As I said in a few posts back, I'm trying to create a similar conversation to what was in the original scene..
And in the scene, Yoda becomes Qui-Gon's apprentice. In this way, I say it without having to go through the whole explanitory process... and it just is stated as "my apprentice"... if I could find him saying "new" I might insert that.
I kinda want to re-watch episode I and III and see if there isn't any more dialogue that I could insert for Yoda. I think I got most of what Qui-Gon has said... your idea of using Yoda's Line "How can this be?" would be a good idea... but I don't recall it lol... where in Episode II is it?
I guess my whole thing with the clones was maybe to Show Yoda's distrust that he was the chosen one... to bring balance to the force... The Clones represent the opposite... that things went out of whack... and that Sidious gained power instead of losing it.
As for "ruining" an iconic moment from the PT, I kinda take offense to that lol... I mean... I kinda liked it after I saw it... ... but maybe I'll put it as I'd had it before...
I'll play with the edit more...
