If ever there was a family that needs some SERIOUS therapy, it’s the three sons of Steffon and Cassandra Baratheon: Robert, Stannis and Renly.
We cannot discount the destructive influence on the elder two of witnessing their parents die at sea in a storm. They literally stood on the ramparts of Storm’s End, hoping to see Mum and Dad come home…. only to see Mum and Dad’s ship be broken apart, knowing everyone on board would drown in the raging seas. (Except Patchface. Why Stannis kept him around is perplexing – the ultimate masochistic reminder of his parents’ fate?!)
Renly escapes this trauma, only to have his own trauma of growing up raised by his brothers (one literally distant and the other emotionally distant) and his castellan.
Nearly all the problems engulfing Westeros right now following the War of the Five Kings, not to mention that actual war itself, could have been avoided had these three brothers been able to actually talk to each other…. y’know, with words and stuff.
