Tess's List is the notepad where Tess tracks her and Joel's smuggled goods, and it sits on the side table next to a gas lantern in the apartment where Joel napped, at the very start of The Outskirts.
Dated entries log shipments from Bill: canned food, Canadian whiskey, bandages, ammunition and bottles of pills, plus a morphine find, a bottle of Scotch Tess kept for the two of them and a Kevlar vest worth selling. She complains about unsorted pills and sardines.
The August entry reminds Joel to take eight bottles of pills to Donovan in the West End and calls Bill's latest delivery weak. Bill becomes important in the next chapter, so the list is your first hint of who he is.
Davidson's Firefly Pendant
Davidson's Firefly pendant lies underwater in a stone rotunda in The Capitol Building section of The Outskirts. It belonged to Melinda Davidson and is easy to swim past.
Evacuation Leaflet
The Evacuation Leaflet is an old FEDRA warning on the right-hand pavement in downtown Boston. Once you climb the collapsed street and Tess and Ellie start talking about the bombing, look by the base of a traffic light a car has hit.
Field Ops Log
The Field Ops Log is a soldier's patrol record inside the Goldstone Building, the tilted skyscraper downtown. Climb the stairwell toward the fifth floor; it lies beside the second dead soldier, along with a couple of 9mm rounds.
Firefly Map
The Firefly Map is a note on a dead Firefly in the subway station downtown, on the stairs between the two escalators. It is the body to the right of the one carrying a Molotov cocktail.
