User blog comment:ChishioKunrin/"Why was Neo afraid of Raven?" An explanation./@comment-80.192.105.94-20150813214203

Fair enough. Not a bad suggestion. Neo likely could tell Raven would be nothing like Yang and that taster was enough to indicate Raven was skilled and strong enough to be a "problem". I do also have a theory Neo has low physical endurance, so this would definitely be a fight she would be unwilling to engage in.
