The question then is exactly who among Sovereign Uriel's advisors is the sharp-fanged impostor. Though Vox Machina doesn't put the pieces together here (having a massive dragon divert your focus will do that), the clue clearly signposts that the dragon is a human character viewers have already been introduced to. When Vox Machina first investigates the mysterious monster up in the mountains, Vex (the group's resident tracker) notes human footprints heading toward where the dragon emerges. The Legend of Vox Machina's dragon twist succeeds by not being quite so.
