He's a member of a cult that resides in Silent Hill, 'The Order'. They use this weird symbol as their logo to put it bluntly.

( she isn't going to tell james to avoid him or that he's a bad person per say because her own feelings about him were mixed. she had empathy for what he had gone through, and in a past life, she knew how the cult treated the members.

they were all brainwashed victims in her eyes. additionally, being here together, and vincent being her only 'ally' so to speak, made her closer to him than anyone else. )

It sounds like you never ran into them, which is strange. However they've been after me my entire life...
