It's always been true on this show that HIPAA has been treated a more of a suggestion than an oath. Sure, no problem, unless it's super important then it's fine, spill your guts. I would be shocked if Maggie or anyone on this show experienced any blowback for breaking it. What bugs me is that Maggie of all of them acted as if she had never heard of such a thing as an oath. The difference in competent, professional Maggie knowing she couldn't tell the boy about his mom against his dad's wishes and her unprofessional behaviour about Teddy 's condition was annoying. She apparently knows the rules but doesn't believe she needs to follow them, if she doesn't want to. As another poster said Teddy is not and has not made any indication that she intends to involve Owen in whatever she decides. I may think that's a mistake but it's her decision to make, not Maggie's.
The "One Thing" was funny and I liked Alex for the first time in a long while.
