chunk: The two Sams realize that the incoming "rescue" team will kill them both if they are found together. The newer Sam suggests sending the other to Earth in one of the helium-3 transports, but the older Sam, with his health declining, knows that he will not live much longer (he has learned that the clones are designed to "break down" at the end of the 3-year contract, their bodies disposed of under the guise of sending them back to Earth). He suggests the younger Sam leave instead. The older Sam plans to die by the crashed rover so Lunar Industries will not suspect anything until it is too late.
