Does anybody remember a scene where Isabelle actually overhears Robert on the phone?

Rewatching the show right now, and I just got to season 2 episode 14, the fair folk and Isabelle tells Maryse that she overheard one of Robert's phone conversations, which is how she found out about the affair. However, I could have sworn that when I first watched the show, there was actually a scene where we see this happen, we see her stop outside a door and he's sitting on the edge of a desk on the phone and then he comes out the door and confronts her and lies to her about it.​​ And when he walks away we see her tare up. But now I can't find any evidence of the scene anywhere.
