Even weeks after his return, Mariner held an enormous grudge about Boimler leaving her for the Titan. Something that apparently played on her mind to the point she left his digital representation to die in her workout routine (one that didn't contain a Tendi or Rutherford either). In "A Embarrassment of Dooplers", we also find out that she's still bothered Boimler left her and expected him to apologize (which he did). This bugs me because she knew it was something that he'd wanted for a long time and made it all about herself. I was curious how other people read it as Mariner seems like a friend who is all take and no give.
