Despite all of the creepy tension that looms in the movie, Searching ends on a positive, heck, even heartwarming note. We see Margot refreshing a page on her computer for an application that she submits to a prestigious piano school.
In an iMessage window, Margot chats with her dad. They joke around as David sends her a picture of them cheesing together at her school, presumably as she's recovering from the ravine fall. David tells her that he's proud of her and that her late mother would be too.
Margot changes the background of her computer to the picture of them together. She then shuts down the computer. It's not quite a cinematic wide shot or dramatic fade to black, but it hit a familiar beat and made us feel fuzzy inside.
