[spoilers] Lucas and his tattoos

[HellsBells]

I have always thought it odd that Sarah never asked about those tattoos. I think this is because the writers had not decided on the tattoos meanings, or were perhaps saving an explanation for a future episode. But this was repeated with Maya, again we do not see Maya ask Lucas about the tattoos even though Lucas stated he would tell Maya everything (okay he lied to her about everything as it turns out!).
