Forum:KB:"I am your father" scene

This just dawned on me a few minutes ago, and now I'll probably have trouble sleeping until I get an answer. :P Vader states that "Obi-Wan never told you what happened to your father." But how does he know that? Unless I'm missing something, Vader has seen Obi-Wan exactly once in the past 22 years, and on that occasion he killed him. So how in the world does he know what Obi-Wan did and did not tell Luke? Or is simply a gaping plot hole with no answer? &mdash;MJ&mdash; War Room 01:21, April 15, 2013 (UTC)
