You know, I still don't get this. What's she licking? The rust? Is she tasting the metal? Is it some form of weird ritual? Is she like the Doctor and can pinpoint the time and date with her tongue? What kind of purpose does it serve? To look cool? I mean, honestly, in a trailer full of ****e this is the most WTF moment for me. The puking scene is the lowest of the low though...
