Yeah S3 didn't have any major medical drama (would have been nice if we actually got to see Tuta do something other than treat the sick child at the inn)
Liukan did quite a lot, as he gave us the antidote for Milich's poisonous flowers and helped cure the dragons, Huan treats Nanami after she gets shot and also has a part in Clive's side quest, and Silva is very involved with Lordlake and Lyon's treatment after she gets stabbed.
Maybe there should have been a moment where Yu helps Ramada recover from the poisoned dart.
It's a mystery how he recovered. You can see him in a later scene when he receives another poison dart, and from what I see in his bio he recovered again after Cray was defeated.
Seems like Cray's darts weren't poisonous...and they were just causing sleep.
But still how they could sneak into Kooluk when it was still guarded? Ramada perhaps had some connections and friends since his time when he was their ally, so they let him in I suppose.
