What i would like is that obi wan finds some jedis somewhere we already heard them name drop quinlan vos's name and Obi sets a trap for vader. So once again Vader is more powerful but is tricked by his master. Obi knows he cant defeat Vader and tries to appeal to Anakin, which we get flashbacks to the good times of Anakin and Obi and theres a split second where he feels Anakin returning. Then blam full Vader full of hatrid so Obi signals for the other Jedi and fighters, and says he has the high ground again.
Vader full of rage slaughters everyone including Vos and the other Jedi.
Obi barely escapes but the rest are slaughtered.
Obi talks to Qui gon somewhere in the episode.
Obi loses more hope and just waits for luke to get older but no longer tries to get close to him... hoping that either Luke comes to him, oif not hes ok with the Jedi being gone. Which would play into a new hope where Obi wasnt looking to train luke and wasnt looking for an adventure.
Vader saying Obi thought he could turn him
Vader saying he was now the master
More Jedi dead and all Obis fault
