@augustaean - Liked for a starter!
Gareth was USED to others coming across Terminus; they had a broadcast going, after all. All helpful hands, or more fresh meat for the slaughter. It took a special kind of someone to accept their way of life, but it was for SURVIVAL.
The woman had caught him off guard, though. Usually, there was a large group or a single lone wanderer. They appeared to be grizzled, accommodated to the NEW way of life. This one, however? She seemed fine. She seemed okay. Almost alarmingly so.
"Hey," He greeted, voice soft in an attempt to lower whatever defense she ( understandably ) had up in the face of this new group. A smile crossed his lips, "I'm Gareth. Usually, we'd be less armed, but there's been increased walker activity around the tracks here."
He glanced around, GENUINELY looking for any signs of the undead. When there came nothing, Gareth returned to facing her way with that trademark ' everything's okay ' smile.
"You're welcome to come back to our SANCTUARY with us... that is why you're here, right?"
