This was sort of a test when it came to the newly enhanced mana sight and mana sensing abilities that Remey had gained at a higher level than she possessed before. It was partially also a way for Walker and Su to make sure that she was doing alright.
They both knew for sure that the way Remey acted when she was feeling tired from making too many potions or she was injured meant that she was going to hide some of it. She would do the same with her younger siblings in the orphanage at times too, and if Remey thought that those very siblings didn't tell them that Remey was too foolish.
The way that Remey found what she wanted to follow was interesting.
She didn't pull at fire mana and try to manipulate it in the ways that Walker would do so when trying to follow manas to track down their origin. Instead, Remey could clearly see the versions of fire mana that she was trying to sense and track.
