What if the twist in LAST CHRISTMAS is that both the audience and Emilia Clarke become convinced that Henry Golding is an angel/a ghost/all in her head but actually he's a real dude who's just improbably perfect

can’t wait to find out if Last Christmas is a “surprise he’s a ghost” or “surprise he’s an angel” movie

So my theory is the male lead is actually the ghost of the guy whose heart she received in a transplant. As in “last Christmas, I gave you my heart....” https://t.co/yXKvDNsCPL
