Lee's tattoo definitelt connects to the pyramid. But it only seems to activate when he's in genuine danger.

Another interesting fact:  I think it's the symbol for fire, in the book (Jenny's)  there are flames behind it. And I think it's not accident that Lee's name is synonomous with the Korean word for fire "Li".
