Interesting photo has surfaced over at Star Bulletin in one of their articles. This photo leads the article and in it you can see Ethan and Juliet.
An interesting line from Jean Higgins, Lost producer. "We really needed a very advanced-looking lab". So I'm guessing this is the Juliet Flashback, "Not in Portland" and that her and Ethan both worked at the same Lab.
