I like Eugene, at first I thought he was poorly acted, but there are ultra dorks out there that would act like him, so I actually enjoy it. I believe he is the groups guilt. They are still trying to hold onto humanity and babysitting this man child I believe is their way to feel better about the inhuman things they do everyday. I wouldn't shed a tear if he got killed, but I kind of get his purpose.
Only other thing that really jumped out was the mayor. She sure didn't want to be in there with the Wolves and I bet it's not for reasons that are obvious. Anyways just a guess based on her reaction.
