The prepper network is Death Stranding's social world — the individuals and communities who have retreated into bunkers and shelters and are surviving independently, connected to nothing, waiting for a connection that Sam is building toward them one delivery at a time. The Sea Otter Suit is the transaction made concrete: Sam delivers what the prepper needs, the prepper gives Sam what his next stretch of terrain requires. The network builds through reciprocity, each connection producing the resources for the next one.

The wandering MC is one of the preppers who chose movement over shelter, who kept traveling after the Stranding rather than going underground. He represents a different adaptive strategy — not fortification but perpetual motion, the refusal to root in a world where roots can be consumed by timefall. Sam understands this instinctively. He is also a person for whom stopping has always felt like the more dangerous option.
