Whatever motions Blue was going through moments before ceased the second he felt a mind focused on him. Falsely identified though he may have been, it didn't alter the tugging sensation of being detected.

He made no immediate move to return any gaze or physical regard, only his eyebrows knitting in a concerned fashion as he became more aware of the distressed swell of emotions directed at him. He was sure he never knew the woman at the source, yet...it could very well possibly be another case of his past-future self. Another "old" acquaintance he had yet to know. That notion unsettled him, giving a grim tone to his features until he became aware of it, forcibly diluting his expression to something mild.

When she had approached close enough for it to have been appropriate to acknowledge her, he did, turning his body partway with his gaze, eyebrows lifting in a blend of surprise and curiosity. Looking at her that way helped little; he had no recognition of her at all.
