who cooks normally?: Twilight.
how often do they fight?: A lot…Maybe 5 times a day at least…
what do they do when they’re away from each other?: Twilight does her normal thing, as well as Sunset
nicknames for each other?: I don’t think Twilight really has a nickname for Sunset, but Sunset calls Twilight “Sparkle", as you may have picked up.
who is more likely to pay for dinner?: I guess they’ll fight over the bill, but it ends up with them splitting it.
who steals the covers at night?: Sunset. She’ll be a blanket hog on colder nights.
what would they get each other for gifts?: Twilight would get Sunset a book what else is new and Sunset would get Twilight something ironic, like she would make her a mock Element of Harmony.
who remembers things?: Twilight. I believe it’s canon, too!
who cusses more?: SUNSET FOR SURE, because I believe Twilight will rarely swear because she’s pretty innocent. And Sunset kinda seems like one of those people
what would they do if the other one was hurt?: Emotionally they would break down and cry together hint hint, eggheadprincess, and if physically, Sunset would be like “Get over it." while bandaging up Twilight, and Twilight would be trying to calm Sunset down when she's bandaging her.
who kissed who first?: I guess we already know that— once again, eggheadprincess , It was Sunset.
who made the first move?: Isn’t this the same question as the one before?
who started the relationship?: These questions are really starting to sound the same, but it would’ve been Sunset kind of forcing Twilight to go along with it.
