Javert 'beating' the child (through sort of understanding him) and winning the hunt...namely due to how depressed he looks at the end of the page.
Note how he does this after acknowledging to the kid that sometimes he wishes he wasn't the cynical one while he normally seems fine to be considered The Cynic.
After the wild hunt, Jareth thanks his roommates for not calling him out in front of the other hunters and essentially asks who wants to give him "The Reason You Suck" Speech for the trouble he caused first. Even if it turns into a CMOH, it hurts to see how Jareth is clearly still beating himself up over the Dark!Jareth thing and maybe doesn't realize how much his friends do care. It may help that Javert of all people is the one who forgives him.
On "King's War" pg 24 the Erlkönig clearly wants to offer comfort to his injured son, but is terrified that in Jareth's injured state he will only hurt him further. The poor Fey looks like he's about to cry.Thankfully Mrs. N will have none of that.
Glinda's reason for attacking the Goblin Kingdom in the King's War is because Jareth made James regent and she still sees James as his canon, glory-seeking, antagonsitic self and declares his only contributions to his own canon to be his futile chase after Sparrow and his betrayal at the end of the second movie that endangered everyone. Up until now James has had the least troubles over his own canon, but it's still getting thrown in his face. Ouch.
Socks the Champion's death.
Even worse, after Glinda is talked down the Conclave reveals they did not intervene because "no wrong" had yet been done. James clearly has the above death in mind when he screams "NO WRONG? NO WRONG?"
Let's not forget those last two words in the arc: "You're welcome."
After spending the day helping him recover, Sara starts to drift off on a depowered Jareth's shoulder. He quickly rouses her a bit, explaining to her what's going on so she doesn't wake up and think he's manipulated her into this somehow. She replies, sleepily, that since he doesn't have his magic right now she knows she can "sleep safe." The stricken look on his face speaks volumes.
The Such Stuff as Dreams are Made On arc is full of it:
Erlkönig: We ruin all we touch. What is much, we devour. What is beautiful, we mar. What is living... We strangle. What is innocent... We shatter. We want, but cannot hold. We seem, but cannot be. We take, but giving... Giving... That is our undoing.
The revelation that Jareth's realm is of "The Unwanted" (his Mother's realm is Winter and his Father's is Summer). Someone give this guy another hug.
In another flashback, the Erlkönig had given young Jareth one last speech before being banished.
Erlkönig: Fight for the ending you want. Somewhere, someone will feel the same and believe. Then, even if you lose, even if you die... You will live. You will live on in dreams. It is the only way to escape. And you must escape. Or there is no hope for any of us.
The end quote.
Jareth: Do you know how some families fight and shout and curse at each other but at the end of they day they're still your family and you're with them to the end of the world because you love them and they love you?
