For the secret dating Ravenās POV, she starts noticing small domestic things in both of their homes that are giveaways of each other. Clarke takes her coffee with milk, and Lexa is lactose intolerant and now there is always milk in her fridge. Clarke, who lives alone, has two phone chargers now, one on either side of the bed. Clarke wears contacts and Lexa doesnāt, and there is contact solution on Lexaās bathroom counter next to Lexaās hairbrush thatās full of blonde hair. Clarke doesnāt give a shit about sports and Lexa is a big fan, Raven comes over to watch tv and have a girls night and all of the recently watched on Clarkeās streaming apps are sports and she has espn on her Home Screen now. All the little stuff related to daily habits that they forget to hide when they get too comfortable! Trademark snacks they love well stocked at each otherās place, stuff left behind from work, the most boring stuff that they themselves overlook but itās so glaring to someone who knows itās not supposed to be there.
