In Babylon 5, for example, a character lists famous bombings like "Hiroshima, Dresden, San Diego" with the first items in the list being real and the last being fictional. This dialog technique of casually tying the past into a fictional future seems to be common in franchises with world-building like Star Trek.
Is there a name for the trope where a character specifically lists two real, historical items and then a third fictional one? That always seems to be the pattern.
