Aeneas did not usually show where death occured, almost ironically. Death, natural or not, still happened without the blond needing to act. They could, technically, and sometimes they did; but the fact remained that beings existed for this job.
So the Incarnation of Death should not remove work from reapers, especially as like their fellow Incarnations, they would rather not broadcoast they did exist. That Death itself, the source, the core, was sentient.
But sometimes, Aeneas did sense a death would occur soon, and the same senses were telling the Incarnation that it could be prevented. Quite a few people, in fact, had different, possible deaths. In a sense, it was like a judgement marked. Shall this soul be allowed to live this life longer? Or shall this be their death?
Usually, reapers did not know all the deaths, or did not notice this kind of case. Sometimes, fate had reapers find a person that might die though, and this was enough for fate to say death should happen. But most often, when Aeneas themselves ended up choosing whether or not this soul should die, either personally or from afar, the blond should have free room. To have reapers come only after they marked the soul to die soon, if it was its fate.
So when Aeneas unmarked the death, the human oblivious to the death they avoided and instead feeling lucky they didn’t cross the street right away, avoiding being run over; the blond did not expect to turn and have a sudden knowlegde they had messed up.
Because now that they weren’t focused on the mortal soul, Aeneas’ senses picked a strong aura of death, blue eyes immediately finding the reaper that emitted it. Their eyes widened slightly, not quite panicked but certainly unsure, and then the blond tugged their hood down, starting to move away.
However, their path was obviously leading to an alley, where less people went by, and Aeneas was not going fast enough to be seen as escaping. It had tempted them, just vanishing; but they knew it would create troubles.
Tenebrae would scold them later, though. So much.
