Wasn't the ENT "footage" MU Vulcans arriving on MU Earth? I inferred Kovich was talking about MU Terrans meeting "teh Prime" Vulcans during the first crossover. But you have a point that it seems to be the example from ENT. IMDB currently doesn't list Nhan for any other episodes this season. But didn't we see some images that showed an aged Nhan?
