huge fan of how isolated they kept robby in s2 because like. he doesn't have anyone. he didn't have anyone in s1, he doesn't have anyone in s2. not truly, not really. it's not the literally no one is there type of loneliness. it's the fact that you're surrounded by people, and you're still deeply alone.
even the people that help him or confront him or reach out to him the most, he barely has. dana, who is first and foremost a coworker before a best friend, who had no idea about robby's abandonment. jack, who's admittedly closer, but I assume is included in "no one knows", + is avoidant, often working, and hasn't faced most of his own shit. not truly reliable.
I mean, that scene where robby is grinning and refusing eye contact and not reassuring jack he'll be okay... and jack doesn't even follow him. just leaves. and later, when dana is practically begging jack to at least say something. do something. but jack is also closed off, so it took that push. he didn't even truly initiate the reaching out.
even duke's connection to robby gets overinflated, and I think it suits the narrative much better to view it as it is: duke and robby are not particularly close. it's implied it's a recent friendship, mainly over motorcycles, which is a recent development in robby's life. and robby, over and over, has to practically plead with duke to stay, have the CT for him, and is generally difficult.
robby is grasping to this friendship because it's likely one of the only ones he has, possibly the only one. and eventually, yes, duke softens at the desperation and comforts him, but it's still just... they're clearly not very close. robby is desperate for connection and unwilling to let it go, he's crying out for help, whoever will help.
him and noelle clearly aren't that close, including the fact that she gossips about something personal to him to dana without a second thought. it's not even a want for robby, the comfort of a warm body in his bed, it's a need. he knows he can't be alone. he can't handle it. but he doesn't wanna get close enough to anyone to be abandoned, so he always leaves first.
yana kovalenko, who is one of the people who cut through to him emotionally the most, is a patient. cassie, who also checked in on him and made an effort, is his resident. the vast majority of people that are considered his "support system" are his responsibilities as well, or at the very least his coworkers first, which heavily clashes.
that's why he latches on so heavy to duke, why duke gets through to him easily, even though he's... honestly pretty surface level, and I assume knows very little about robby's inner self, just as everyone else. all he really knows, from that day, is wow this hospital is draining. but that was enough for robby. because robby is desperately lonely and duke is not a responsibility or a coworker. and duke is older, and robby is subconsciously always searching for a figure like that. someone to guide him. a mother, a father, a mentor. anyone.
anyways I just feel like most of robby's relationships, (even heather in s1 and sometimes especially her,) get wildly overinflated. and it does a disservice to his character. one of the core parts of his character that explains many of his motivations are how completely lonely he is.
