I watch this show every week but miss things from time to time so I check this site but I keep reading that Rossuao or however you spell her name was infected but I don't remember hearing about that. I know her team was and she was a little crazy but what do think happens to someone in the woods alone for 15 years. Her daughter was kidnapped she had to kill her own team and she kept hearing the others voices over and over but never saw them of course shes nuts. I also have to think if someone was infected why would her main worry continue to be finding her baby after 15 years. Again I could have missed a part saying she was infected but I always just thought she was just crazy.
There is absolutely no proof she was infected, but the inference is strong with last week's ending. Claire now looks/acts like Rousseou II, and Dogen says she is infected, therefore Claire is acting like Rousseou because both are/were infected. But it is all based on the last couple of minutes of last week's ep. Things can drastically change after just the opening this week. Heck, right now we have no proof there actually is an "infection". We'll see.
