How did Isaac and Miria became immortals? In one of the final episodes, Chez notices Isaac is immortal when he's trying to save him from falling off the train.
Isaac also got shot, and beaten down.

However, he didn't drink the "sake" he and Miria stole from the mob, did he?

How did he and Miria became immortals?
Same way as Gandors and Martellos.


  Box with elixir of immortality went from what's-his-name brewer to Dallas Genoard, who then left it at Gandors' place. On Scilard's orders, Dallas recovered the box, but then he was robbed by Isaac &amp; Miria, who took the box with them to Firo's inauguration party, where all present drank the elixir.
