With three months of being physically close to her crush, she was able to stow away her shyness and focus on helping Jayce, though it would be a lie if she said she didn't prefer if it took another couple of months to remove the collar.
Every morning since Tess said she could remove the collar, Jayce would visit her place early in the morning and give her an hour to work.
The only times he didn't visit were when Oliver needed him for something.
Jayce figured that Oliver had someone monitoring him, probably the girl who could use shadow magic, but he doubted it was twenty-four-seven monitoring.
Unlike him, people needed at least four hours of sleep to barely be operable.
To not draw suspicion if they decided to watch Jayce early in the morning, he limited his time to one hour.
On top of that, Jayce used as little demonic energy as possible to use his {Demonic Eye of Truth} to constantly check for any hidden mages.
