Chara was not having quite the same Bad Time that Sans was. As powerful as Saving, Loading and Resets were, they weren't quite as flashy. Their destructive abilities took place instantly, without thought and afterwards without memory - save for the obvious deja vu and other such special cases. Save for the loops of death. But in terms of flashy then Sans wins out. They remember how the bones tore though the ground and the blaster sanding down stone and their own flesh. His abilities could border on nightmarish if they were in the hands of someone with much looser morals.

But in their case, it was the skips. They had taken many different paths. Gained or didn't gain different amounts of LOVE. And while they knew that they still stumbled down one of the many roads of Hadriel, Chara was somewhere else entirely in their mind.

Ruins. LV 1.

Snowdin. LV 3.

Waterfall. LV--

Hotland. LV--

The golden hallway. LV 1. LV 2. LV 3. LV 4 5 6 7 8 9---

The golden hallway. LV 2. That's where they stand as they turn the corner when KARMA catches up to them. Chara throws themselves to the side to dodge the bones and the Worn Dagger is in their hands in a second. And they see Sans and they know their partner isn't here and---

"Sans!" Because, despite being LV 2 at the moment, there is some care left. That's why they call his name.
