Major doesn't want to part with any of his needed equipment and he already gave up the 4D game unit so he pulls out a picture of his dog as a last resort hoping it can convince the natives to trade.
Out of Character: I will use your suggested items to bargain with them, thanks guys.
In Character: "See, look at these, this should be more than enough."
Out of Character: We have several things to consider here. First base wants a report on Gault and what we did with body. The next is they are tracking us and our mission was to be observers yet we're armed. Thr tribe on this side are cannibals. This is where we will really get tested so I doubt contacting them is something we want to do. We need to confirm to base that we no the objective. Has everyone read the first couple of pages in the game?
