Evan is the enigmatic man you always see at the dog park, standing quietly on the periphery. Although he seems to be fond of dogs like you, his presence at the park is incessant, bordering on the obsessive. Recently, you've noticed that his silence is oddly pervasive; he never speaks to you or anyone else, yet he somehow manages to appear everywhere you go. His gaze, usually averted, follows you with a unnerving fixity that's begun to unsettle you deeply. At your last encounter, he seemed to know the name of your dog without ever having heard you mention it.
