Lady Jessa, Crisel and Imelda were just eating slowly as they secretly watched Tyler and Lanie eating. Tyler remained cold and serious while eating like what they used to see but what shocked them was the way he treated her and the way she treated him. In their whole stay inside the castle, no one dared to talk to Tyler in that way nor looked at him like she does. They aren't allowed to talk to any member of the Royalty except when the Royalty talk to them first and when they are greeting them as a respect. They can't also look at the Royalty eyes.
When Tyler entered the Regnum, he was carrying Lanie. Mr. Blue was already waiting for them at the gate. They used the secret route to enter the castle without anyone noticing. They couldn't enter at the main gate of the castle because it would attract attention from the people of Regnum. Royalty is very private and no one sees them except the people working inside.
