Lost in Space, Found in love

Astronaut Ashley Grant found her husband in bed with another woman and he pretended to be his own twin. She smiled, said nothing, and boarded a one-way mission to a black hole. Now, years later, she's back. But when her remorseful husband begs for forgiveness, she calmly introduces herself as Ashley's twin sister. How do you apologize to a woman who used relativity to outrun your betrayal? Some lies launch you into orbit, others leave you stranded in space, forever.
