Going home to Alexei would mean that they had to take the moonchildren with them, and that wasn't really something that resonated well with them.
Carl, for one, was all for killing the moonchildren. If his mother could die, then there was a way to eliminate indeed the men that had been a pain in their access, no? He hasn't claimed to be the best man, but Carl had known pain.
All his life, he had lived alone, left in the woods to deal with too much. Gaviria, who he had trusted turned out to be his uncle and his mother, was the falci. It didn't even help that there was nothing good that anyone knew of his family.
It was like they were cursed. This situation reminded Carl of what Angelo had told him about Hera. The woman had been so hysterical and crazy, but she had relaxed eventually. Maybe this was a test, but this was the kind of test that made Carlos Median want to rip off the mountains.
