Poor kid left Canterbury so fresh, I didn't want him along, but he really came into his own these past two weeks. He'd died in the night. No point bothering with these pricks at the Citadel now. We head into the city tomorrow.”— Emmet's grave quote
Emmet was a member of the search party that was Searching for Cheryl.
Emmet cut his leg on a piece of super mutant metal architecture, and later died.
Emmet is only mentioned in Fallout 3.
