You should try to watch it again. IMHO it’s the best thing that happened in the SW universe since TESB. It also provides exactly what’s missing in the PT about Anakin, Ben and the Jedi.

Han is 29 in ANH, so he’s between 7 and 10 during the Clone Wars. He’s likely to have seen a Jedi at some point (I’m pretty sure Genndy intented this little boy to be kiddo Han without confirming it, like “it’s your theory dude, think as you wish”. I need to check his commentary track about that). Han just got cynical afterwards.
