There's definitely a different aura around her, changing from friendly to a cold, heartless woman. Who or what shaped her into this is completely unknown, but Cricket's assessment may be onto something. There's an attitude about her that screams non human, whether it's herself or the experiences she's been through.

And then Cricket drops the ball on her, causing Marie's stern expression to falter for a moment. She listens intently, feeling sympathy and admiration towards the boy's perils. However, the circumstance is relatable and Marie knows that she's been okay with letting people die if it meant she could live. Survival. "You care so much about other people, even at the expense of your own life. I used to be like that as well, but different events shape us and change the course of destiny. Regardless, I won't try to talk you down anymore from the task at hand."

She pauses, thinking about his other statement. What if the Thing comes back with them? There's no other choice in her mind that she'd kill the party in an instant. "Our paths diverge here, Cricket. Good luck with your goals." Her voice isn't brimming with confidence, but rather intrigue and mystery. She wants to see what will happen, how the event will change them, instead of genuinely wishing for their success. There's a turn in her step, planning to leave very shortly.
