My predictions for Episode 6:
Mando visits Luke and Grogu. Luke is so reliefed to see him again and begs to take Grogu with him because Grogu has eaten up his whole food supply. There is no drop of blue milk available within 30 parsecs so that Luke had to switch to green milk which he has to import from Ahch-To for way too much credits. Now the kid is going for creatures taller than himself. He even started speedruns with Luke's X-Wing to satisfy his desire for racing and to find some new harvest ground. Force ghost Yoda too complains because the child will not listen to "a strange old guy who does not remember how to form sentences correctly any more". Din talks with Grogu and explains to him that he cannot take him with him because he is up to help his pal Bubba to spoil some baddies wearing fancy masks. Grogu immediately clings to Din's leg and does not let it go any more. Din is left with a difficult choice: Either cut his leg off to get rid of Grogu or take him with him...
OK, and in Episode 7:
Din and Grogu arrive on Tatooine. They help Bubba to get rid of the Pykes. All plot lines are resolved. There is more than enough time for that because the final ep is 350 minutes long. In the end Grogu sneaks away and eats the Rancor. Fennec finds him sitting in the dungeon, wiping off his mouth. She puts down her rifle, smiles and says "You little rascal!" End credits.
Post credit scene: Loki arrives through a dimension portal. Garsa welcomes him and when he asks her where he is she responds: "In a galaxy, far far away." Loki grins and says, "I think I'm gonna like it here! Do you mind me bringing some friends?" The Avenges theme is playing - fade out.
