Breaking of the Sacred Seal - S3-E23
Continuity mistake: When Echo is warning Pegasus not to move closer, in an overview shot, there are two aides on his left. One is a few meters next to him, and the other is a few more meters ahead of the first aid. Just under a minute later, when Pegasus says "Okay, I was kind of with you until that last bit", both aides to the left of Pegasus are side-by-side. (00:10:55 - 00:11:50)
