As she watches him leave, Heidi’s eyes fill with tears, and she heaves a sigh of relief — and perhaps of regret. But when she looks down at the cutlery on her table that had been neatly, horizontally arranged on her napkin — spoon, knife, fork — before Walter sat down, she sees that the fork is now at an angle. Heidi’s jaw drops.
That idea had been thrown out in the writers room, “almost as a joke, like —
and then she looks down, and her fork’s askew,” Bloomberg said. After they decided to do it, they still weren’t positive it would work. “Is it going to be corny, or weird, or confusing?” Bloomberg wondered. “But then when I saw the cut, I was, like, ‘Oh, that works great.’”
As for its meaning — whether Walter actually does remember Heidi, but pretends not to, or whether he just has an ingrained tendency to mess with people — well, we’ll have to wait for Season 2 to find out.
Horowitz said the cliffhanger is meant to put Homecoming’s larger themes in sharp relief. “How do we know who we are? Is our identity determined by our memories or something in our bones?” he said. “Depending on how you interpret the ending, it maybe says something about how you interpret the season in general.”
