I don't agree on this one. I want him to turn back into a baby in the end. My worst case scenario is that they don't and then they kill off Gideon.
I understand this and the fear that they will kill him in the end than make Giles stay, but I cannot help it that I find this idea so creepy that they take a fully adult person with adult thoughts and actions and memories and erase this to deage them to make them a baby again.... But the aging up was creepy to me too and the sped up pregnancy of Zelena.
