If Kos got under Tate's skin so much, why was it Kos who initiated the physical altercation over and over? It seemed like the exact opposite to me: Kos wanted to talk smack, but he couldn't keep up with the pace, and because Tate schooled him in every exchange Kos resorted to stuff like push him, choke him, try to pull his pants down, go for the face, etc. Sounds like he's the one got heated.
