Episode 2 (S02E02)

Rosie is obsessed with it being Christmas despite it actually only being mid-February, constantly pointing at December 25th on the calendar, dragging Si to buy a Christmas tree and obsessively watching Home Alone. When she discovers another day marked on the calendar – President’s Day at the end of February – Em and Si wonder if celebrating President’s Day will distract her from talking endlessly about all things Christmas. In 2007, Em and Si are no longer talking at all, except to argue and shout in front of Ben. They openly discuss with their friends whether they should split up, until the situation finally comes to a head and months of pent of frustration is released in an emotional showdown. (BBC)
