Dr. Anton Vanko keeps a laboratory inside Stark Industries. He keeps his composure when Peggy Carter and Edwin Jarvis stroll in carrying a stolen doomsday chemical. He turns the sample over, precise and unbothered, and names it in a breath: a lanthanum carbon alloy. Clever work and rather unstable. Where a lesser man would flinch, Vanko reasons. Before the war, only three refineries could forge an alloy like this. The Navy tore down Franklin Chemical. Eagle Star switched to diesel. That leaves Roxxon, and with one clean deduction he hands Peggy the thread she has been chasing all night.
He is not finished. Jarvis, ever the optimist about explosives, asks whether the thing is still volatile. Vanko corrects him with a scientist's care. Not volatile, no. Active. Still humming with low levels of Vita radiation.. Peggy needs no lecture on what Vita rays can do.
