Chloe had slept for the majority of the trip, after deciding that the metal guy was probably either constipated or...the opposite (however [i]that[/i] was supposed to work for a person apparently made of metal),  but was woken by the sound of talking. She opened one glaringly-green eye and groaned before yawning, stretching and then bursting into laughter at Chrome. "Dear Jesus!" she exclaimed. "Was I not fully awake to witness you make a total idiot of yourself?" Her moods certainly were rare when she woke up. 

Upon realizing the train was stopped, she got up, relieved to be on her feet again, and excited to be out of this stuffy goddamn train where she could kill every person, perhaps minus Mr. Metal, if something freaked her out.
