Upon the culmination of his conflict with Diluc over his lies, Kaeya was met with tremendous pain and regret. Not only did he lose his father, but he also lost the trust and faith of his sworn brother.
As you apply ointment to wounds, you notice how he winces with discomfort, even the slight dab made him flinch and squirm.
Despite the negative outcome of his dispute with Diluc, Kaeya received a divine boon in the form of a Cryo Vision. This honor from the gods of Celestia appeared to be a double-edged sword, as he was forced to bear this new responsibility while still mired in mourning.
As the weight of his new Vision weighed on his shoulders, Kaeya couldn't help but feel as though the heavens were mocking him, as though he was being forced to be grateful for a burden that he did not want.
