I think that Phoony changed in a bad way. not necessarily for him, but for the oomans. Phoony is more serious about his missions. He is more active in stead of being lazy like in the beginning.
Jack changed in a good way. His engineering skills are more developed. He fixes the skreep and pirate ships.
