Move along nothing to see here...

The film is set in Winter/there's a lot of snow so you have that

I cannot underestimate how RED timothee chalamet's nose is in this film, it was filmed during the winter months and there's a lot of external shots which being exposed to the cold means...you know

there's also a lot of side profiles of his nose which is always *chef kiss*

twice he gets exposed to ice cold water and just...NOTHING in the next scene? One was when he gets his head dunked and the second he mentions swimming 4 miles in ice water?? this really is the type of movie to just add a sneeze from the cold in I was so disappointed lmao.

it's implied that he sleeps outside a lot in the snow and cold like C'MON.

Thankfully, the time back home is a normal hour, so they can call them. Except maybe they are travelling with others (and sharing the same bedrooms) or maybe their voice is so shot they want to conserve it as much as possible - so they message their partner and explain they want them to call but to just describe their day to them or something. When the partner asks what's up they (half) lie that they just really miss them, but they can't make any noise themselves as it's very early in the morning.
