If you can think of a ship, i will answer these questions for them
who cooks normally?: I feel at times that Jack would try to cook for Pitch and be all house-wifey about it. However. He would pick things that are absolutely specific to the health of ones teeth and would get really picky about it and end up making something… Not so good.
how often do they fight?: Ever so often, they are really snarky with one another, I feel like they would get into a lot of snarky battles with one another.
what do they do when they’re away from each other?: Jack works with the teeth and Pitch works with the sand. Sadly. They’re both very busy. But Jack send his Mini’s to go bug the hecks out of Pitch. So he never forgets him.
nicknames for each other?: I feel like Jack would have more then Pitch, but Pitch would have a few secret pet names he only uses in personal times.
who is more likely to pay for dinner?: Pitch would have to be the gentleman, but there’s NO taking Jack out to dinner, he’s so picky.
who steals the covers at night?: It would be a battle of the ages.
what would they get each other for gifts?: Jack brings Pitch new scarves and goggles and Pitch finds tooth cleaning products from around the world. Little technologies and such that Jack doesn’t get to see while he’s so busy.
who remembers things?: Jack is the Guardian of Memories, and Pitch seems a lil aloof, so in this verse, it would be Jack.
who cusses more?: Still Jack. Always Jack. Though, it’s only ever so often, he’s pretty subtle about it here.
what would they do if the other one was hurt?: All hell would break loose. That’s just kinda it.
who kissed who first?: Jack definitely kissed Pitch first. No more waiting on that.
who made the first move?: Pitch would probably be the one to take it a step further.
who started the relationship?: Jack. I bet he was just kind of like ‘SO EVERYONE, PITCH AND I ARE DATING NOW’ and he spit out whatever he was drinking, half chocked on it and was just like “WE ARE?”
