Jade wasn't exactly one to believe in luck; she liked the idea of karma even less. She figured that people who blamed everything bad that happened to them on some all-powerful force were idiots who couldn't take responsibility for their own actions and that the people who praised a higher power for their good fortune were deluded.
That being said, Jade would admit (to a select few…under pain of death) that Friday the 13th has always been good to her. For one, it was on the 13th that she finally agreed to let Beck take her out, who, as many people have annoyingly pointed out, she is lucky to have in her life. There is also the pleasure she gets out of beautifully and thoroughly pranking everyone (mainly Sinjin) whenever the 13th fell on a school day (and sometimes even when it didn't.) Most importantly, however, if Jade were to be completely honest with herself and possibly with the help of a fever induced delirium, she would forever be thankful for that 13th back in 2006.
The day when a stranger saved her life.
