Oliver and Butler

Kevin, Suzie, and even David would be shocked to the core if they saw the crazy, cold-blooded smile which formed on Mark's face when he exited the room. There was no trace of the previous warmth he showed in front of the group. He looked like a beast getting ready to hunt. 

Walking down the corridor, he muttered, "The butler ha. I don't know this new guy, but it seems like he is taking things more seriously compared to my brother. Let's have a nice chat with him." And made his way towards the main hallway. 

Entering the hallway, he looked around for the stairs leading to the first floor and saw the board showing the stairs. He made his way up and when he did; two men guarding the floor stopped him from entering near the entrance of the first floor.
