DANY/DROGO (you so love me :p):
who is the big spoon/little spoon: Drogo big, Dany little.
what is their favorite non-sexual activity: Riding. Drogo would cross the Dothraki Sea with her a thousand times just to show her everything.
who uses all the hot water in the morning: Drogo would let Dany.
what they order from take out: If they did that sort of thing? Meat. Lots of it.
what is the most trivial thing they fight over: Who gets to be on top? >.>
who does most of the cleaning: the servants/Dany's handmaidens. In a one on one situation, though, Drogo would probably expect Dany to. If at all.
what has a season pass in their DVR: if they had DVR? I imagine Dany might.
who controls the netflix queue: If they had one, Drogo would let Dany.
who calls up the super/landlord when the heat’s not working: Drogo. And if they don't fix it, he'd slit their throat. >.>
who steals the blankets: Dany can have them. A khal needs no blankets.
who leaves their stuff around: Drogo.
who remembers to buy the milk: ...I think Drogo would.
who remembers anniversaries: Drogo, but I think they both would.
