I have to catch up on CW so i cant comment on the last few episodes , but i want to say it could be interesting to see Order 66 from the pov of the clones, especially Rex. I've said it before and i'll say it again: if there's a clone capable of questioning that order and walking away, it could be him. I could see Rex having an argument with Anakin before the march on the Temple, and leaving. Anakin having an attachment to Rex lets him go. Ahsoka i feel might be way gone by the time Order 66 rolls on, be it that she dies or leaves the order for some reason.
