When Angel saw a black hole like an abyss appear in the mirror, he understood that he was being watched.
Earlier, when the Black Earl entered the Hanging Jail Stairway, he had also seen this mirror and even left a mark, but nothing happened to him. Why was it different for Angel?
Comparing their differences before and after entering, the answer was actually quite obvious. There was only one reason, and that was the oil painting.
Angel had destroyed the painting and taken the round wood from it. This clearly provoked some hidden presence in the mirror, and the moment Angel came into contact with the mirror again, the entity immediately noticed him.
The dark abyss presented in the dressing mirror was surely the entity's doing.
The goal was no other than to 'force' or 'lure' Angel into the mirror. As for what awaited inside, it was certainly nothing good.
Therefore, when Angel saw the abyssal passage in the mirror, he immediately chose to retreat while sealing off the mirror.
