Aliens Speaking English: The White Star meets the Drakh, making First Contact between the two races. After Lennier sends them language files, they begin transmitting a message in Minbari. Only one problem: Lennier sent them language files in Interlac, not Minbari, which reveals that they have met the Minbari before.
Do a Barrel Roll: "Skin Dancing", which involves smaller ships flying as close to a larger enemy ship as possible to avoid taking fire. The White Stars do this while accelerating so they can pick up enough speed to escape before they can be shot down.
Loophole Abuse: The Warrior Caste have driven the Religious Caste from several of the southernmost cities on Minbar. Many of the Religious died from exposure before reaching shelter. Minbari do not kill Minbari, but apparently driving them out into the snow where they'll probably die is okay, because it's not you doing the killing, is it?
