Zach Baskhi

 is Brad's brother.

He shows up at Mythic Quest Studios under the guise of celebrating his brother's birthday. In fact, though, he's there to take a look at the business from the inside. Though David takes to him instantly, Zach is unable to fool his brother.

Soon after Zach arrives, Brad begins to deny that it's his birthday, and he starts muttering under his breath about a "Kate" and "pig's blood". But Brad can't get anyone to believe there's a problem with Zach because he's outwardly amiable.

When the brothers are finally alone in a room together, Zach finally drops the act and admits that he's there to raid Mythic Quest for its parts. He makes Brad beg to keep MQ intact -- but then refuses to commit to any course of action.

Later, Jo follows him into an elevator, where he gives her two minutes to "ask the question". He spills the beans on the semi-mysterious "Kate", revealing that he possibly does have exactly the interest in slicing up MQ Studios that Brad feared.
