Curate, connect, and discover
(potential) ways people find out santos and whitaker are close/living together:
whitaker calling santos "trin" in front of their coworkers, santos not batting an eye and answering to it, and both of them pausing suddenly when they realize what happened.
santos putting an arm around whitaker's shoulders and ruffling his hair at random intervals throughout the day.
one of them instinctively stepping in front of the other when a fight breaks out in the hospital.
accidentally falling asleep while leaning on each other in the break room after a long shift.
santos handing whitaker a shopping list while passing him in the hallway.
one getting injured/passing out and immediately asking for the other when they wake up, still half-asleep.
^ alternate scenario: getting put on meds and saying something disgustingly sentimental. if it's whitaker, santos would get a bit emotional in the moment but will definitely make fun of him when he's sober. if it's santos, she'll be stuck wondering why whitaker looks so pleased with himself until someone tells her what happened.
discussing what they're going to eat for dinner while everyone is clocking out.
