Of the dozen-and-some tree people who are lucid and talking, only two speak any English. One speaks French; three Russian; another two Spanish. The rest don't speak any language that anyone's recognized so far. Three are huddled in a deep discussion, so it's safe to assume they share a language, but what it is is anybody's guess.
Another handful are awake but not talking yet; their reaction time is extant but slow and it's hard to tell if they're too overwhelmed to parse questions or if they just don't understand. Two seem to be conscious but completely unresponsive to any stimuli save for autonomic movements.
According to one of the English speakers, one of the tree people died in the woods and three more didn't make it through the night.
The remaining twenty or so haven't woken, or haven't woken long enough for anyone to get any information out of them.
