After numerous unsuccessful attempts to make the mechanism work, Krysty Wroth calls upon her mutant strength and forces the door open.
The only exit leads up a long, spiraling metal staircase which eventually comes out in a secret door built into the attic chimney of a partially fire-destroyed dacha.
Rick protests at first, revealing that his ALS is no longer in remission and is making him progressively weaker, but relents when it becomes clear there is no other option if they are to find tools.
Meanwhile, in the Russian government capital (located in the suburbs near the heavily bombed ruins of Moscow), the recently promoted Major-Commissar Gregori Zimyanin has been following reports of the group's actions.
The tools are stolen easily, their cases not even locked, but taking the American flag trips an alarm and alerts Museum security.
Zimyanin's forces attack the dacha as repairs are nearing completion, and Rick asks to be left behind with cans of gasoline and a pyrotab to cover the escape.
Ryan and the others are able to hold off the Russians long enough for the door to be repaired; before they leave Rick, wrapped in the rescued American flag, asks for one last favor, to hear The Star-Spangled Banner before he dies.
