Uhura goes across when everyone has already crossed. On the other side she will use her light and analyzer as usual.
Seeing that Uhura has chosen to go last Major will go after Seth but he will not hold his torch in his hand, he will ask Uhura to shine the way for him and keep his torch in his pack.
Uhura will go up to the natives and ask them if word from the chief has come about our arrangement for the canoes to cross the river. If it has she will call the others up to have them take us across. If not she will ask how much to be taken across.
Major takes a position next to Artemis and Uhura. While he does not want to appear aggressive he does have his hand resting on his gun just in case.
Major shows the natives a photo of his pet and offers it to bargain for the crossing. He will say it brings good luck.
