I don’t think it will be answered anytime soon, but my main question at this point is who got Grogu out of the Jedi temple before order 66? I wonder if it’s someone we know, or someone new?
My bet’s on Jocasta Nu. She survived the earliest phase of the purge and dedicated the remainder of her life to preserve key Jedi artifacts and information in order to (eventually) rebuild the Order and train a new school of Jedi. We know that she didn’t survive in the end but she could have taken Grogu with her when she went into hiding.
