That headcanon is GOD TIER WOW WOW WOW I think another way you could look at it is in the thick of their rivalry everyone ELSE calls them the work spouses and they’re like PFFT PFFFTTT NO
(Anonymous said to elsaclack: ok ok but what about Amy refers to someone else being her work spouse,, like Rosa or Terry, and Jake is all jealous and offended like excuse me i am your work husband)
like early in the morning as people are really getting settled and getting into the swing of things, jake is only barely coherent and is still half-asleep when rosa walks in
amy: hey rosa i left a macchiato on your desk but they were out of your sweetner at the coffee shop so you may have to add some before you drink it
rosa: oh sweet thanks work wife
jake, who has been face-down on his desk, suddenly springing up like he’s been shot: excuse me, what did you just call amy
rosa, unflinching: my work wife
jake, pouting at amy: i thought you were my work wife
amy, refusing to meet his eyes: i can have more than one work spouse jake
jake, still pouting, to rosa as she walks by smirking: does that make us sister wives
