The "immortal radar" mentioned in other questions does not explain how the Kurgan knew Connor MacLeod was immortal.
- He was far away on the other side of a valley before the 1536 battle against the MacLeod clan
- He knew that Connor was among the hundreds of people in the battle
- He also knew it was Connor well before the battle began because he made a pact with the chieftain of the Fraser clan that only he could kill Connor.
So how did the Kurgan know Connor MacLeod was immortal?
