Has anyone noticed this before? Petra has some sort of hidden power that she won't show unless she thinks you aren't watching. I've never seen her do it when looking at her head on or when people are really close. But if you get behind her at a certain angle she will make her knife levitate. At first I thought it was a glitch but there is a very specific sound that happens when she makes it float so I think this is intentional. If someone has seen this before and it's well-known then I apologize. What do you guys think about this?
