Oh! Maybe it is alcohol too… he did mention "he'd murder for a Manhattan but he'll take a water" when we first met him… Did he drink the champagne when they were celebrating? I can't remember that detail, but I don't recall him actually drinking any…

But Karen was meant to be annoying.

It was! No argument about that.
But it was also a bit fishy, coming right out of referring to the whole hurricane thing as a "gamble"…

Exactly!
It was like his "go-to" past time… while he's in the car… weird…

Yup… those were my red flags. Were they a bit obvious? Maaaaaybe… but I thought it interesting that he was talking about gambling one second, and the instant he's out of sight he's set up a poker game.

Well it's only his second episode, and we're still getting to know him so there's still time for the flaws to appear. I personally have a feeling he might very well have a gambling problem… so that could very well be an issue…
