ONE SECOND! i do hope we are all aware that francis saying "you dont have friends you have admirers" was his angry, drunken cursing and not actually the complete truth (especially with the line being off-screen and intentionally not in the show). there were crew members that james thought as friends but who weren't actually, at least not to the extent he thought (des voeux, dundy, stanley even). and james intentionally used his charm and acting/pretending to make people like him and to get up the career ladder. which is why it hit a nerve. but that doesn't mean he didn't have friends.
franklin and bridgens were there. barrow (here please note that the son ross spoke with was probably george barrow, not john barrow jr, who was james' friend. george is also the one with the rumored scandal, not john), charlewood, cleaveland, the coninghams and more still existed. we just didnt see them.
francis knew james for a few years, a lot of that time on different ships and not particularly being best friends, a lot of that time being angry and depressed and in self pity, envious and jealous to an extent too. what he knows of james before the expedition and his personal life in general is the exaggerated stories that james tells and what the admiralty, the same people that treat him like shit, says
james is on a ship with 200 men, many of whom he never met before, men that look up to him and EXPECT him to be a leader. the other captain hates him. then franklin dies, and others die and james has to try even harder. has to show everyone (including francis who he knows looks down on him) that he knows what hes doing, what hes capable of, that all is well. this is the environment francis sees and knows james in. the only other times likely at fancy admiralty dinners where james had to try and meet the expectations of the higher-ups and himself as well. so of course this is how james might seem to francis and probably to others too. but they were fighting, francis wasnt making a factual objective analysis of james
francis doesnt know what james is like with his family and his actual friends, when hes himself. francis is judging the persona james puts up, and hes judging the fact that james puts up one in the first place. thats the only james he knows. they really get to know each other after that, francis sees him after that. francis literally tells him he sees him differently then
yes show james is way more lonely and repressed than historical james, but hes still james and hes still loved and francis realizes that too in the end
“In the war film, a soldier can hold his buddy—as long as his buddy is dying on the battlefield. In the western, Butch Cassidy can wash the Sundance Kid’s naked flesh—as long as it is wounded. In the boxing film, a trainer can rub the well-developed torso and sinewy back of his protege—as long as it is bruised. In the crime film, a mob lieutenant can embrace his boss like a lover—as long as he is riddled with bullets.
Violence makes the homo-eroticism of many “male” genres invisible; it is a structural mechanism of plausible deniability.”
