Lexie was a bit taken aback as Cielo walked a bit between she and the masked man. It was a protective gesture, and Lexie hadn't expected that. A reasonable person would have started backing away slowly, not made direct eye contact, and given up their goods. That's what you were supposed to do when you were mugged right (well, that and scream like hell; but, in the woods who the hell would hear you scream?)
Masked-wonder started babbling about a mission and not causing trouble etc. Lexie wasn't too certain what to make of it. Ciello continued to ask questions and for the life of her, Lexie didn't understand why. You run away from freaky people and you don't look back. Or you call for a psych consult. This wasn't the sort of 'I have problems with alcohol' issues; this was I'm walking around in a flippin mask issues.
Clamming up, Lexie crossed her arms and chewed her lip. She didn't know which way to run and she didn't want to leave Cielo.
