Han Dong didn't immediately bring Nicole back to the holding cell.
His only aim was not to reveal the special traits of 'containment' in front of anyone. Since the matters related to 'the Town Mayor' had been mentioned in the detailed directory, coupled with Derry Town with its myriad of strange residents, it was challenging to rule out if some Clerk was spying on every resident. Han Dong would avoid using any hidden power if he could.
He took Nicole back to his dormitory's bathroom and turned the shower faucet on full blast.
A lot of water washed over Nicole's body. Her severed tentacles on her right arm started to slowly re-grow and heal, and the pain was also nullified.
Of course.
Because her body was so weak, Nicole had difficulty maintaining her human form.
