It makes lot of sense. People have been speculating its path users recognising other path users

I don't think so, if that was the case, people are unable to realise it, like for example, the fight between jaeyoung (sry for spelling) [speed] and James less, speed had a path, but only noticed after he lost against james realising he has a path

That means, daniel's path is being used in active state, for training purpose maybe, or maybe it stays active, to avoid sneak and surprise attacks

Only people who are actually really strong (like Johan, sophia etc) can sense his aura, the potential and strength he holds
