Agatha/Rio and/or Seven/Raffi for the ship game?
Who accidentally pushes a door instead of pulling/vice versa
Agatha. But she makes it seem like she planned it All Along. Rio pushes by accident but it still works for her because... She's Death. It annoys Agatha, but she's thankful it just works and doesn't explode.
Who doodles little hearts all over the desk with their initials inside them
Rio, but carved with a knife. It's sweet but also looks ominous.
Who starts the tickle fights
Who starts the pillow fights
It depends on the mood either one could start the tickle or the pillow fight. But they would definitely take it too far.
Who falls asleep last, watching the other with a small affectionate smile
Since Rio can forego sleep, Rio just spends the time Agatha is asleep watching her. This used to creep out Agatha, but she's used to it.
Who mistakes salt for sugar
Both. For different reasons, Rio because she honestly doesn't know better since... Cosmic Being. Agatha, because she's distracted, and then Agatha will loudly complain about it until Rio changes it magically.
Who lets the microwave play the loud beeping sound at 1am in the morning
Who comes up with cheesy pick up lines
Honestly, both! They both come up with cheesy pickup lines, but Rio is the one who does them sincerely. Agatha does it either to troll or be sincere.
Who rearranges the bookshelf in alphabetical order
Surprisingly, it's both of them. Agatha is a Nerd. And Rio, for all her chaotic sensibilities is actually a Lawful neutral.
Who licks the spoon when they’re baking brownies
Who buys candles for dinners even though there’s no special occasion
Who draws little tattoos on the other with a pen
I think, with Agatha's restless hands, this would be Agatha.
Who comes home with a new souvenir magnet every time they go on vacation
Rio, if they were invented when they were dating.
Who convinces the other to fill out those couple surveys in the back of magazines
Ooh, I think it would be Rio. Agatha can be too cranky about it or thinks she's too cool for the whole thing.
Who accidentally pushes a door instead of pulling/vice versa
Raffi, I think. I feel Seven's still careful about these things despite looking and playing like shes a rogue.
Who doodles little hearts all over the desk with their initials inside them
Raffi, I think. Seven would be too appalled to do that, inside, she's still the same stuffy ex-Borg on Voyager.
Who starts the tickle fights
Who starts the pillow fights
I would like to think when Seven becomes comfortable, she would start the pillow or tickle fights.
Who falls asleep last, watching the other with a small affectionate smile
Seven would fall asleep last since sleeping still doesn't feel natural for her.
Who mistakes salt for sugar
Ooh, I think. Raffi because she gets distracted in the kitchen.
Who lets the microwave play the loud beeping sound at 1am in the morning
Raffi, because she forgets about and Seven because she's running an experiment.
Who comes up with cheesy pick up lines
Seven would do it because she thinks its expected of her.
Who rearranges the bookshelf in alphabetical order
Seven of Nine, would do that!
Who licks the spoon when they’re baking brownies
Oh, I think they both do, but Seven appreciates it more since she's never done it. Raffi introduces her to the practice.
Who buys candles for dinners even though there’s no special occasion
I think this would be Raffi, Seven wouldn't think of replicating candles.
Who draws little tattoos on the other with a pen
Raffi would love drawing little tattoos and maybe Seven would like the sensation. It's very new to her.
Who comes home with a new souvenir magnet every time they go on vacation
Who convinces the other to fill out those couple surveys in the back of magazines
Seven because she dutifully completes surveys that she sees.
