No, nothing of this has been confirmed. He could pretty well be hiding the whole time or even long gone from the Aperture. I mean, it's very vague to afirm anything. What about all those paintings and that weird sound? The same goes to the Earth thing. The Combine may be ceased from the planet but that doesn't mean they dont exist anymore. We just saw some shots of a clean Earth and that's it, And like some said here, the Xenias creature have already adapted and made into the ecosystem. You were afirming things that were not confirmed, based on some very vague matters and because of that they are just assumptions. Look at these, we can just theorize http://half-life.wikia.com/wiki/Doug_Rattmann http://half-life.wikia.com/wiki/Timeline_of_the_Half-Life_universe Please, use the proper wiki: http://combineoverwiki.net/wiki/Doug_Rattmann http://combineoverwiki.net/wiki/Timeline_of_the_Half-Life_and_Portal_universe
