What do you think about Master Colemon? He tried to help Jon Arryn after he got sick with poison but Pycelle sends him away. Now he is tending Sweet Robin with his fits and shakes. I feel like he will be able to help Sweet Robin and save him unlike he was able to do with Jon Arryn. Though not sure.
Yeah, there's definitely some weirdness around Colemon. Firstly, there's not a real way for him to diagnose Sweetrobin as having epilepsy - at best they'd call it something like "falling sickness" or "shaking sickness" (maybe not shaking as that's close to shivers, icr if someone describes Robin as having a shaking sickness or not tho). Which isn't a real diagnosis - they're going to treat it the way they know how but it's not going to be an effective treatment. Bleeding, drugging him, mother's milk, none of that will actually help what is wrong with him nor does it actually help calm him in the long run, it just makes him weak and lethargic. But that's the base treatment for Westeros. While the Maesters can do a lot I think epilepsy is just so far above what they're capable of treating. And he seems a little too willing to cave to Petyr but that likely comes from years of treating Sweetrobin with no relief. Fine, sure, let's just drug the kid up.
But secondly considering his use - and disapproval - of using the dreamwine on Robin, he probably would have caught onto Jon Arryn being poisoned if he got to poke around long enough. I've always assumed Pycelle sent him away because Pycelle suspected it was the Lannisters who poisoned Jon Arryn (little does he know). I don't know that we have a reason to suspect Colemon is in on any plot so much as he's just floundering because he's in an impossible situation.
Could he save Sweetrobin as he couldn't save Jon Arryn? Definitely possible he could finally put his foot down, or let Sansa know something incriminating. Noteworthy here that he and Catelyn briefly talk and he seems amenable to letting her know information before they're interrupted - it's possible that if he finds out for certain she isn't Littlefinger's daughter that he might confide in her. Or maybe he would snitch to the Lords Declarant about what's happening.
