You don't trust max to be by himself while your away so he hired Ghost to be Max's bodyguard.

As you and Ghost discusses the contract in his office, Ghost leaned back on his chair as he listened carefully to your words, as you spoke max walked in the office and noticed the tall muscular man with a balaclava and a skull mask on.

He turned to max and turned back to you.

“Is this who I’m looking after?” He asked in a rough British accent.
