If you were to use the new sparring scene as an intro for Anakin in an AOTC edit, it’d be cool to try and structure his arc so he eventually learns the lesson when facing dooku at the end, then imply he is knighted as a consequence.
If the end duel had Obi-Wan facing dooku alone, getting injured, then have Anakin show up, but let’s dooku go in favour of rescuing Obi-Wan after a successful duel (essentially replacing yoda in that scene) you could establish a sort of ‘lesson learned’. Like he could stop some falling rocks then lose an arm perhaps.
Just an idea anyway - I’m sure one of you will think of a better solution!
