Well, this is sort of a weird picture, so here's the equally weird story. Last summer, my sister and I went totally Trekkie for reasons that we still do not understand. My sister is still a Trekkie, but I went on to get a life (not really. I took up comic books instead, which is why I'm here today. Thank you, Gene Roddenberry! )
Anyway, my sister and I got to talking, and you know how Spock says he is Vulcan with a human mother? Well, what if he had a sister who was human with a Vulcan father? Thus was born this weird little drawing. I was going to do all sorts of followups and stuff with Spock's sister (I assume that she had a name at some point that I have now forgotten), but I got bored.
