Hill had originally thought that William's minor trouble was due to being watched by a group of bigshots overhead, which made it difficult for him to say much to Hill.
Although as friends, apologizing is normal. But under the gaze of all gods, the future deity of justice and fairness might have some things he couldn't outright say.
William possibly wanted Spencer to first convey his apology, and after returning to Teraxil, he would formally communicate with Hill.
Hill could feel that Spencer hoped he would temporarily refrain from bringing up the matter.
Although a bit unclear, Hill promptly agreed, for his anger towards William had calmed down a lot over time.
He had been so angry before because at some point, Hill had come to consider William a friend.
If withdrawing to the position of allies, Hill had to admit that William's actions were not at all problematic.
From the perspective of the alliance, it was quite commendable for William to have shown such an attitude.
