King Daniel Into Darkness: I can't speak as to the character in the fan film, but Stephen is from the novel Enterprise: The First Adventure by Vonda McIntyre. I've always wondered what it would be like if Stephen met Sybok (and with a family like that, no wonder Spock was so messed up, and his father so pushy for a Vulcan son!)
YES!! That is the book I read. Boy...but that was a long time ago. I recall that Spock was VERY ashamed of his cousin, Stephen for showing emotion. As I remember, Stephen was jealous of Spock...because Spock actually could feel human emotions (since he's half human-but suppressed said human emotions) - and Stephen was actually faking many of his human-like emotions. I KNOW that Vulcans possess emotions...but this particular book kind of played it that Vulcans didn't possess very strong emotions or were limited emotion-wise. At least not emotions exactly like a humans.
