Their connection begins when Solo boards a derelict slaving craft to find that its cargo of Wookiee children had escaped and all that was left on board was a severely wounded Wookiee in the pilot’s seat.
Han was ordered to skin the helpless Chewbacca alive but refused. A court martial and an escape ensued as a result of this insubordination. Chewbacca later swore that he owed a life debt to Han and wouldn’t leave his side.
And that was the beginning of a beautiful friendship!
So the question is, will one of the spin off films feature Han Solo and will it cover how Han and Chewie became best mates?
