After the call with Kelvin, Lucas made the decision to officially fire him and the system revoked its privileges to Kelvin. Unfortunately, the latter wouldn't even be aware of this and Lucas had not notified him of them in the first place.
Originally, Kelvin would have found out on his own about the system skills, as long as he got into trouble within the store. However, there was no incident that had occurred warranting that. Even the event with the extremists had ended with Lucas interfering at the last moment.
As such, Kelvin had no knowledge of the power he held. Nonetheless, it didn't matter at the moment.
After removing Kelvin, there was now one free slot out of two on this employee page. Melissa was registered as an employee within the store simply for her safety. Speaking of Melissa, she was still in the Mertens family's custody, but Lucas had made a phone call and asked for hed to be sent over the next day.
