This question contains spoilers… (view spoiler)[Did Robert know that Gwen was John's psychiatrist when he approached her at the bar? I'm confused how he was able to keep his cool with her when he thought she was the cause of Gabe's death, gifting her his special ring etc? I read this as an audiobook which is a format I'm not used to so that might have affected my understanding (couldn't flick back to particular passages etc) (hide spoiler)]
