When Spike started to grow on the new episode, i thought he would just stay like that for the rest of the season, because it would show that puberty was a normal thing, and i thought that was the moraal of the episode, but then when he started to grow more and more and get more greedy, i knew that the moral of the episode involved greed not puberty. I think that the morals for the newer episodes are getting more important, because i can relate with many of the issues now in season 2, unlike in season 1, where i found it kind of hard to relate to them.
