well, they were on and off for two years because he's an older guy and she has daddy issues. they clicked physically and just kept coming back to each other, which is his m.o. they both cheated on each other and eventually called it off as they're incompatible and max doesn't do legitimate relationships anyway. max is capable of separating business and personal, but if she was at all snippy with him during the casting process, he honestly wouldn't have offered the role to her. if you want to roll with saying it's something she let slip later on, that's fine.
