The opening text should really come before CC, although having read Ice’s suggestion I totally agree with it. It would do wonders pacing-wise, yet setting a precedent for this episode distinctiveness with the later time-jump.

I honestly found Option 2 really commendable as it currently stands and I wouldn’t like to lose the first practice scene. I think having it helps establish visually the important aspects to remember of the main clones (Hevy is hotheaded, Echo plays by-the-book, etc.) and serves as a better introduction for 99, Shaak Ti and the drill instructors. And I felt it flew really well as an opening act, I never noticed how the ten minutes almost flew by, so its length shouldn’t be a concern. Moving the scene with the clones and Shaak Ti to earlier felt seamless and it led smoothly into the talk with Lama Su. It could have been like this in the original episode with no issues.

I feel the final test could have use for an additional establishing shot at the beginning (also the ARC Trooper’s lines sound a bit low, a minor nitpick). Also I’m divided on if 99’s pep talk works best before or after the failed test. Putting myself in the place of a newcomer, it could be a bit jarring or anticlimatic if after this emotional moment the squad unceremoniously fails anyway. It could also transition better, continuity and thematically-wise, from 99 overhearing the drill instructors to meeting Hevy and lifting his spirits.
