So It’s Gambling

As far as I’m aware there is no back story to show Aiden as a gambler so I’m assuming this is a development from the new writers to work a way out for this character?
And now check forging too!
What always kills me is how seemingly anyone can just stroll on into the Dimera mansion. Like someone of Stef’s stature with many enemies wouldn’t have at least a guard on duty and state of the art alarm system. Although maybe Aiden could turn that off with the keys?
