Q: In X-Men Origins: Wolverine (2009) there is a scene with Kayla and Logan driving in the car when they approach a bridge with two trucks going opposite directions stopped, blocking the way. Logan gets upset and goes to nicely ask the guys to move. They give him grief, but before he rocks their world, Kayla intervenes, calming the truck driver. The driver then turns around and leaves; there is no incident. What is the purpose of this scene? Is it to show that Kayla has some kind of power? From what I've read, she doesn't have any powers that allow her to manipulate other people. When Logan and Kayla get back into the car, they have an exchange about it where Kayla denies having power because Logan still got out of the car. So what was the point of this scene?
