I seriously thought it was the veins/arteries in her hand...but that's just me, Miss Non-Observant here. Where did Anna have the tattoo? On top of her hand? Because I didn't see Season 1 at all...I have the tape and I'll check now.
Well my memory can't be great either...it took me almost 3 weeks to remember about this thread, and then ask what the verdict was! I though maybe that would spark an answer from somebody! Don't forget to post your verdict!
