Interview with Heather McComber is the thirty-first video on the DarkHarvest00 channel.
Chris and Alex interview Heather at a local Starbucks. They learn that the chest she owns was once owned by Marc, her grandfather, and that she was forbidden to look inside of it as a child. They also learn that Marc was an assistant scientist at the Atlantic Test Site in the 1950s, and got dementia shortly before his disappearance in 2001. Chris and Alex ask to have another interview with Heather at her house, and she accepts.
- At 7:35, the secret jingle from The Legend of Zelda series is heard, presumably from someone's cell phone. This is the third time The Legend of Zelda has made an unconventional cameo in the series.
- Alex mentions that he attended BlizzCon 2011.
