The temptation to have a drink right now is eating away at Marie, but she needs her composure and clarity of mind for what's she's about to ask Cricket. It's never easy bringing up bad news, especially since Cricket clearly has a friendly relationship with the mechanic. Alas, she can't let him willingly throw himself into danger, at least not without trying to talk him down first.

"He's a very nice man, yes. However, I met with him a few days ago and learned that he was trying to go home and kill some sort of alien creature. I don't know much about these kind of things, and I wouldn't mention it randomly to anyone, but I wanted to inquire about your involvement in this affair." She isn't going to immediately wail into the young man about his decision-making skills, but letting Cricket know that she knows might make talking about the Thing easier. A middle ground instead of sounding optimistic or belittling.
