I honestly didn’t know which brother to side with the whole book. Neither is bad. Isaac is over confident but not necessarily arrogant. He did seem to be the better weather observer overall, though Joseph was correct about the hurricane. Joseph, it was stated, wasn’t overly impressive in any manner, but seemed to be a diligent worker. Joseph was envious of Isaac’s success, and Isaac saw Joseph as almost a trigger as it pertains to his wife’s death. It was a really bizarre dynamic honestly. Sad they ended up never reconciling.
