Tam “knows” that Rand is the Dragon Reborn. Jordan said that Tam has all the clues he needs to figure out that Rand is the Dragon Reborn. Whether or not Tam will admit it to himself is another matter. Jordan said that Tam merely finding Rand as a baby on the slopes of Dragonmount wasn’t enough of a clue—even if Tam were familiar with that prophecy then, few people think about those things or expect them to happen literally to them—but that, plus the fact that Rand has disappeared off with Aes Sedai who say he’s important, and the fact that the world is going crazy, should give Tam enough information to make the conclusion.
