That's a typical reaction Malcolm gets when he calls someone out. He's used to it.

Letting instinct guide him is actually something that he can do. Malcolm closes his eyes for a moment, concentrating. What he's being called to do is kind of insane, and he hopes Jim won't freak out again.

Malcolm moves to the wall of the barn and begins to draw a square on the wall with his bloody finger. Once he pulls away, an almost invisible field seems to grow out of the place where he drew the square, expanding until both he and Jim are inside of it.

"Huh," Malcolm says.
