You should check out the word you used. This post isn't necessarily incorrect, but the word you used before is ONUS. As in, the duty, the responsibility. He may have to put more work into this to get the relationship to work, but its not in any way his DUTY to do so.
If he wants things to work, it is something he's going to have to take responsibility for.
Onus is a duty OR responsibility, using only google to look it up. Interestingly, if you check with various dictionary sources, you get different definitions entirely. It turns out onus is a word that has many meanings. Who'd have thunk it?
The most common first definition of the word is "difficult or unpleasant task," which I think accurately sums up the situation. It's certainly the sense I used.
Accountability is overrated, especially in situations like this. It follows from the western fetish for punishment and vengeance. I'm not sure how revenge is useful in this context. If you care about someone, you try to help them. Period. If you can't because of other emotion, you admit the other emotion is stronger than your ability to care about that person. It's all rather simple, but we value judge the caring to the extent that not caring enough is something only bad people do. Since we aren't bad people, it must be someone else's fault. BS self justification, but lying to ourselves so we can judge others is fundamental to the human condition.
You keep going on about Faye not letting Angus do whatever, as if I haven't already acknowledged that. This is a relationship based comic. It's unlikely that Angus is a serial killer, or will die in the war. (Though, Angus getting killed would be the ultimate "fuck you" from the author to this particular character.) Barring death, its fairly likely that Faye and Angus are going to interact again. To what extent remains unknown. Perhaps Angus is the new Padma, and last week was his final appearance.
My analysis of the situation has always been contingent upon the continuation of the relationship. It simply doesn't apply otherwise. Your argument that Faye doesn't all doesn't apply to the circumstances where my analysis applies. I also addressed that scenario at the outset. It's a null result. Game over. Relationship end. I really don't understand why you think anyone would have suggested that Angus could force a relationship on Faye. The idea that he could emotionally support her against her will is, frankly, ludicrous.
