Regan wished to return to Mazic when he had heard Derrick that the matter regarding Evelyn's marriage with Arthur that happened years ago would be put to rest.
It meant that Derrick was no longer interested in fulfilling Arthur's demand and it was perhaps because Derrick also found all the ministers and Regan's words reasonable.
Arthur was from an enemy country and he had not helped them much for now so they should not fulfill any of his demands.
However, the next morning just when Regan was discussing with Rex when they should return to Mazic, Regan was called to Royal Palace by Derrick.
Regan didn't wish to go but Rex persuaded him.
According to Rex, Derrick had helped Regan by putting a full stop to Arthur's demand so they should also show some respect to him as a king that he deserved. And since he had called Regan to Royal Palace, he should go there once.
Hence, the same morning Regan was inside Derrick's chambers.
"You can't leave Mazic yet."
