Lalafell and Dwarves... Plot Hole Potential?

[Daralii]

Well if it is a Beast Tribe, for me we're likely to never see anything more than these models (with a few tweaks for any kind of leader for instance), because that's how beast tribes kind of work.

So I went back to the stream and what put me on that track is what Koji says (roughly at 1:45:00 mark); "what kind of model are they using?"
I really think that the picture is just there to make the connexion between the two, as they say "Never without the helmets but it's a keynot so we can take it off".

If they're identical to their Source counterpart like all the other races(based on the cinematic at least), then NPCs taking off their beards and helmets so that they can emote during cutscenes is hardly a stretch. If you have a base model that's rigged, it makes sense to use it.
