i have two ideas for you one: nightmare trope?? preferably Jameson has a nightmare and Avery wakes him - but up to you!! and also, maybe one night, it’s raining, hard, and Avery comes up to their room to find Jameson standing on the balcony, and he’s already soaked through. maybe, after Avery gets Jameson back inside and warmed up, she uses that word - Tahiti, i think? i can’t remember - which means Jameson has to tell her what’s up. maybe it’s something to do with like his childhood, or something about Emily??
sorry if that’s too much detail but your writing is really good
