Nautilus
Cold War (1x7)
:
The Nautilus and the Dreadnought both become lodged in the Arctic ice. Nemo offers to tow the Dreadnought out, if he can use their forge to repair their broken U-bolt. It’s the only way any of them will survive. Millais, in fact Nemo’s childhood friend Billy, knows that Nemo is headed, ultimately, for London and the Company’s offices.
