If the Ewok movies are sort of prequels to ROTJ, then how did Wicket forget the SW language equvialent to english?. Also, wouldn't the rest of the tribe realize that humans are not a threat after being around the Towani family and Noah?.
Possibilities: He didn't forget- he's just playing dumb around Leia until he's certain she can be trusted. The tribe might, after bad experiences with the Empire, assume that armed humans are a threat until proven otherwise.
I'm pretty sure the official reason given was that the Towani family weren't actually speaking Basic.
The Towani family didn't speak Galactic Basic Standard (which almost exactly sounds like English) to the Ewoks, they spoke Bocce, but it has been "translated" to English for the audience, because children don't want to watch 90 minutes in a made-up language. The actors spoke English, but the Towani family's native tongue which has been used in-universe by the characters was Bocce.
If we assume that the Ewok movies are based on the memories of the Towani girl that she tells years later, then it can be inferred that the events of the second film are more fictionalized than the first. A lot of what was shown in it still happened, but Wicket never learned to speak Basic.
Excellent way of putting it into context. The story itself was something of a folk/fairy tale within the SW universe (hence the voiceover), even if the events themselves are accepted as having 'really' occurred in whatever canon the Ewok stories are accepted. What we saw was a retelling, rather than the events themselves - which, to a certain extent, I sometimes consider the PT to be.
Its an EU story turned animated film for the wee little chillins who wanted chibi wookiees. It makes no sense in LA SW films
I think the tribe is smart enough not to think EVERY human is safe to be around just because of one good experience.
