Because of Umbra, Shane was aware of the intelligence beasts with higher quality could achieve even at lower stages, causing him to feel extremely uncomfortable at the moment.
In common cases, beasts at the awakened stage would possess the intelligence of a 6-year-old human child, but these were already considered exceptions!
If he was not wrong, Umbra with an [Extraordinary] quality was already capable of thinking like a 3 to a 4-year-old child, even though he was at the Wild stage.
'What if there is an awakened beast with a high intelligence due to a higher quality?'
This thought made Shane feel extremely uncomfortable. Generally, humans didn't take Basic-Primordial Dimensions' beast tides as seriously as tides within the Intermediate or even Advanced dimension.
