Oh man this thing bugged the crap outta me! Like, either those ice cutters are complete ass holes, or else Kristoff's running off to live with trolls traumatized the HELL out of a bunch of big, burly men who've lived with the horrifying belief that their young apprentice froze to death in a lake and none of them realized it until hours later.
Haha, so funny! I had also wondered if the other ice harvesters noticed that Kristoff was no longer with them! Yes, I also think it's best that Kristoff went to live with the trolls. He needed a family that loved and cared for him.
I was also puzzled why none of the guys kinda NOTICED a little boy went missing, and possibly freezing in the cold?? And then trolls kidnapped him and claim him as their son -- the end. (great comic btw!)
It's kind of a 'blink and you'll miss it' situation. It happens during 'For the First Time in Forever,' when Anna goes out the gate, I believe. Admittedly, I had to look it up on Google, because I kept missing it too.
