I second Viner16's request. It may not have to be that specific, but it would be kind of interesting to see something that runs counter to the darkness of the game as a sort of dramatic irony or something. Kind of like the end of Cloverfield.
Or they could do something where Clem or Lee are recording on the camera they found in a down time moment capturing something very innocent and light. Same effect, but more focused and potentially less hokey. Some other characters could pop in too.
PuhChewyChomp's suggestion is kind of funny in a really sad way though
