In some of the recent blogs I have seen people say that we learn that Radzinsky knew about 815 and the losties from something that happened in "he's Our You". I have no idea what this is referring to. I have watched the episode three or four times now and I still am not sure. I heard that it was in the Oldham-Sayid scene so I watched that scene ten times and still do not know. Maybe I am an idiot. Probably. Could someone help me out and explain what gives away that Radzinsky knew?
Sorry if I misspelled any character names.
