Well you know Jake's pet project that he is aiming towards so he will want to take steps to try and work towards making that happen, which I know will require multiple quest all around the world to get certain entities attention.
Obviously he will need to figure out if he can trust his wife with his secret. If she would even want to leave with him when they go.
Make awesome plans on how they will work out getting the shard from the world ship without Gods coming after them and blasting them from existence.
Figure out how to create interoperability between this world's old high level tech and his fighter ship if he finds it to make sweet ass upgrades to it. Obviously will have to make nice with Zora without causing his wife wanting to cut a bitch. Of course make his new ship he gets on this new planet to be as kickass as he possibly can when it's not merged with the others.
Probably try to keep from getting killed by the two Troll clans that want him dead.
Lastly just be awesome while irritating the Old Man any chance he gets.
