Ah, yes, that was another big WTF! Not only was she wearing a lab coat (which I believe has her name on it, and identifies her as an employee of New Amsterdam), but she also had her hospital ID on, and she's DOCTOR HELEN, from the teevee. No effort whatsoever to be covert in that little errand. She might as well have walked up to a cop herself, handed him/her a business card and said, "I'mma take this woman in here to shoot up...you'll be here waiting to arrest me when I come out, right?" I do wonder, though, who dimed her out. I have a mental image of Castro following her, peering around corners and whatnot.
