After finishing his business with Sihan, he returned to his room and stayed there to make his next plan to deal with his reputation and turn it to his advantage.
He spent most of his time inside his room, only to come out after Ellen and Alea called him to start his preparation for the banquet.
He also got invited by Phyrill to take care of his appearance at the banquet. Theo accepted it since he had nothing to do other than thinking about his response to others in the banquet.
It took him an hour to get ready. There wasn't much different from his last appearance other than the color of his tuxedo, so there was no more shock from Phyrill and others.
As soon as they finished, Theo and the others were picked up by the driver to go to the venue.
