The Sound Updates or "Flashes" in The Other Session are, obviously, the updates that have sound. There are currently 3 sound updates. The first two are in Google Drive because there was no YouTube Channel for The Other Session yet. The third update redirects to a YouTube video. It is said on The Other Session's Tumblr that the author shave figured out how to embed the video in the comic space and will do so from now on. A fourth sound update is currently in development. It will be a game, as Matthew says on the Tumblr. It is the reason The Other Session is currently on Hiatus.
