An interesting episode, but I'm not sure what the point of it was, from the ambush on Tatooine, to the spider-peril later on. Wasn't keen on Baby Yoda eating the spawn, though. Unless all this is to underline that the Child is developing an ammoral outlook. After all, it's being exposed to a lot of death and killing. Perhaps that's the lesson here? And the need for morale guidance from another teacher?
Also, interesting how the episodes so far directly connect, instead of being standalone and disjointed like some of the Season 1 ones were.
