We don’t know who raised the Alden Ehrenreich version of Han Solo, but it probably wasn’t Wookiees.
Clearly, if it had been, he’d have a much different origin than the one we’re going to get when Solo: A Star Wars Story opens next weekend.
Somehow the new movie would have to account for what we saw in Revenge of the Sith.
The original trilogy never presented Chewbacca as a surrogate father, but if the prequels had done that, any Solo film set between the two trilogies would have had to deal with the concept.
