What is the photo of Robert and Laura Petrie taken from DD’s cellphone where he has his arm behind Gillian? What are u guys talking about? I’ve seen the professional official pic but no others. Can u guys help me out?

It comes from this video, which is a bts from the official photoshoot. It’s quick, but at some point, you can see them taking a picture on one of their phone, and it never came out, so it’s safe to assume they did it to keep it for themselves. Like the two professional and platonic coworkers they are.
