Thanks. Two interesting things about that. First it's weird that they're saying "mole" - it could mean a number of things. It could mean that it is an Other already infiltrated in the group of survivors. If so, it would be interesting to know where this person is typing from, since that's the only terminal we're aware of among the survivors. I guess he could be missing from the group temporarily. Or it could be Walt. He could be a mole among the Others. Given his experience with the supernatural, he could be faking his belonging to the Others while remaining loyal to the survivors.
A mole implies someone who has infiltrated a group, not a liar. So whoever is on the other end of that chatting session technically should not be limited to merely lying to Michael, but being actively among another group under a false impression.
Secondly, the legal document displayed after the mole animation is very interesting. It's a letter from a WHO (World Health Organization) guy to I'm guessing the legal team for Hanso. It has to do with guarding against threats to the general population, speaks of a research facility in Zanzibar (an island off the east coast of Africa), and it implies that the WHO guy had been unpleasant in previous correspondence.
It looks like maybe he was recently "persuaded" to switch positions and side with Hanso. Maybe it was because of the recent donation, maybe it was because of something more...personal or supernatural. Maybe Hanso is buttering up the worldwide health community to set them up for whatever inventions he's going to come up with. Maybe he has lab rats everywhere, including in Zanzibar and on the Lost island. Maybe maybe maybe.
