10 Doctor Who Moments Deeper Than You Think
4. Amy Pond's Dropped Ice Cream
The Steven Moffat era is full of short extra scenes that add layers of understanding to his overarching storylines.
For Doctor Who Series 6, he wrote several of these shorts under the banner "Night and the Doctor", which were designed to show what the Eleventh Doctor got up to while Amy and Rory were in bed.
To sum up, he goes on a bunch of dates with their daughter River Song.
One of these shorts (Good Night) sees the Doctor return from a date to find Amy struggling to sleep. They discuss how having the epicenter of a cataclysmic temporal event in your childhood bedroom can lead to some very confusing memories.
To centre Amy, the Doctor tries to remind her of her saddest childhood memory. "Did I drop an ice cream? That can't be my saddest memory", she muses.
"Remembering ice cream's always sad", the Doctor responds.
The fact that the Doctor says "remembering" rather than "dropping" is key to the hidden meaning of this exchange. In Moffat's Silence in the Library/Forest of the Dead, the last words of poor Miss Evangelista are "ice cream", which is often mistaken for "I scream".
See, remembering ice cream is sad.
