Those last couple of pages: definitely feeling-sorry-for-the-troll time.
I'm seeing, I hope correctly, resignation in that last gesture and not just cowering in fear: more 'OK, I know what you have to do, but I'm not going to watch.'
-- I had been somewhat expecting all through this that Hilja-troll had some sort of plan, and had thought at first that she was deliberately in ambush and was then running to somewhere specific from where she could carry out further plans. It doesn't seem to be that, though; both the attack on Cat Man and the dash away from the cottage seem to have just been a panic reaction, attempting to get away without any actual plan. So whatever was going on with the Thing in the Package, Hilja must not have expected to herself become trollified -- either that, or she was indeed under the control of somebody/something else, which did expect that to happen but didn't care. If the second, I really hope she was somehow unaware at least most of the time of what was going to happen.
