Graham looks at Jordan in The Substitute. Why?

[Taricco]

When I saw episode 6 - The Substitute, there was a scene where Jordan is walking out of the Principal's office. Meanwhile Graham Chase is sitting in the waiting room and Jordan passed him by. They both looked at each other. Graham looked after him. Did he know him or why was he looking. Did they both know who the other one is?

I think they recognized each other from Vic's classroom. Graham stopped to talk to Vic about the Lit magazine and Vic was working with Jordon. Vic then proceeds to tell Graham how much it pisses him off that no one bothered to notice that incredibly smart kid who just left never quite learned how to read.

Now that I think about it, I'm surprised that they didn't recognize each other when they met in Pressure.
