I just knew that people were going to read into Vader's servant in that way. And once again...
As for some other nuggets? I like how the temple on Jedha involved the Ancient Order of the Whills, which in itself was the angle for the inclusion of Chirrut Imwe and Baze Malbus, both late of the Order. The whole concept of the Journal of the Whills is something that dates back to one of George Lucas's initial treatments for Star Wars. And the Order of the Whills seems to link into the Church of the Force which we were introduced to in The Force Awakens
. Chirrut's faith in The Force leads you to believe that had circumstances been better for him, he may have been a Jedi. And Baze seems to have had more of a crisis of faith in The Force following the sacking of the Temple by the Empire. This, plus Jedha's status as a holy city, combined with this reverence for the kyber crystals is really fleshing out our concept of The Force in some interesting ways. It's not just magic or midichlorians anymore.
And what about all of the shots from the trailer that didn't make the final cut?!?! OMG!!! Jyn mouthing off to General Draven? Gone. Krennic walking through the water? Gone. Saw talking to a younger Jyn (what will you do when they break you)? Gone! Krennic's "Power is immeasurable"? GONE! That is some cutthroat editing if I've ever seen it.
