As for what that ability was…
It wasn't quite as easy to quantify, but if Di Tou had to take a crack at it he would say that he always had a sense of who he was.
No… that was too vague.
Thinking back to his actions over the past day or so, Di Tou realized he had made a lot of choices that he might not have made otherwise. It wasn't that he was being more impulsive, but almost like he had lost some of his fear and reservations and instead did what he felt was right. To an extent, it was being rash, but to another extent, it was Di Tou trusting his own judgment. The judgment he made in the moment, instead of second-guessing himself and acting off of what ifs formed from him getting in his own head.
