The hole doesn’t make sense in the last panel and it’s wrecking my brain.

When you are in a dark place, a single voice can bring light.

No, I think what our Canadian friend is saying is that the hole in the last panel has an incongruent perspective. When the camera is top side looking down at the hole, the hole shape should be mirrored. If you consider the character topside looking down in the third panel, the little tail of the speech bubble hole is on their right, but in the fourth panel it is on their left.
