I noticed somthing whilst watching "Dead is Dead" the other day. 34 mins in to the episode. Frank is asked by Ilana "what lies in the shadow of the statue?".
Frank is prompted to walk over to her, by a man in a red shirt with long hair, whom we havnt seen on the island yet. He comes running up the beach to Frank, shouting
"you're back, thank god. They found guns".

Is it just me, or is that 'Eddie', from season 3, episode 3 - Further Instructions -
Remember? Lockes new buddy who he picks up hitch hiking, who turns out to be a cop?

Please help me - I'm going out of my mind as none of my friends are as bigger lost fan as me, and they cannot remember the episode.

I think I would have noticed that...But I'll check!
