This represents "Kick in the Head"because of what is happening in the scene.

Lets get some background, first. This is a Saturday night, just after a Spitfires home game. The team has another game early-ish on Sunday in Ironton (imagine a Philly-to-Pittsburgh drive), so they're going to bus to Ironton overnight. The rest of the team has left the locker room already, so Eli sneaks down to give Sebastian a send-off. Sebastian's teammate, Don (on the left) had forgotten something in the locker room, so he went back to get it, walking in on Sebastian and Eli smooching. (This is the moment of "Kick in the Head." Not physically, of course.) Eli flees the scene, and Don confronts Sebastian. They argue (seen here). Don is not really homophobic, just underinformed. Eventually they come to an understanding and Don agrees to keep Sebastian's secret.

I didn't get the tail posture quite right for "aggression," but the facial expressions are correct enough. Don's ears are forward, indicating anger or aggression, and his teeth are bared. Sebastian's ears are back, indicating a defensive posture, but his teeth are bared for anger or aggression. Tails should be straight out for anger, but I wanted to make sure you could see the tails in the pic.
