We got 13 marines here. We got a Foreigner in the crowd. Would Hokusai need to be added to tags, then?

Probably not. That marine might be sus, but they still look like a marine - no visual indicator of Hokusai, which we'd need for a tag.

Obviously the top left Marine is the imposter here since the other 12 is identical.
