Lars goes with the group, heading through the mountains. He keeps a wary eye out, once in the mountains. He has no intention of underestimating the dangers here.
Specific Action: Major will wait to see what response Uhura gets but in any case he will take the mountain trail. He will also use the guide to see what he can expect.
Lars continues to walk down the trail, keeping his eyes out for any danger. Once past the tourists, he draws his handgun and loads as many shells into it as he can, then replaces it hidden on his person.
Since everyone is moving forward Major will do the same but he first hides anything that might give away his true mission.
Specific Action: Stop and listen to what is being said. If they seem harmless enough Uhura will follow behind with the group.
