Pour out some Romulan Ale with the gang as they mourn the loss of Lieutenant Tasha Yar in "Skin of Evil." It's a solemn occasion (well, relatively) as we discuss Yar's legacy as well as the nature of oil slick mud puddles (aka: evil). Alex would like to say a few words, Marcy cries crocodile tears, and Cameron just wants to know why. Thankfully, Marcy brightens things up with a quiz on crystals. All this and more on this week's episode of Green Shirt! Engage!
