Great blog post! Welcome to the Merlin Wiki, Ksrouse94.

I too have been wondering about the things you mentioned. Morgana being immortal all of a sudden baffled me. However, I think that she might have become immortal (at least immune to mortal blades) when Aithusa healed her. It's also possible that the Triple Goddess gave her this kind of immortality since Morgana was the last High Priestess of the Triple Goddes. But I think it's a shame that the show never explained it at all.

As for her powers slowly growing. Merlin was supposed to be the greatest sorcerer of all and a great exception among all sorcerers. He was raised in a home where his powers weren't oppressed, so he learnt about it from the very start and was emotionally well balanced. Still, his powers weren't fully developed yet when he arrived in Camelot. Gaius and Kilgharrah guided and helped him and he became more powerful over the time, learning spells and getting familiar with his destiny and powers. Despite all the things he had been going through he had some stability in his life which was provided by Gaius and Hunith, plus the others he met over the years and who adviced/informed him.

Morgana, on the other hand, had nobody to guide her. I will never excuse her actions and I never ever believed that others were responsible for her madness and evil actions (aside from the fact that I think that the show runners ruined her once so great character) but nevertheless she never had anyone to tell her about her true nature, and the only person she trusted with her fear (her nightmares and visions), before she met Merlin, was Gaius. Gaius kept this secret, yet he never really guided her and so her powers were oppressed until they somewhat "exploded". And then she met Morgause. So Morgana had no chance to come to terms with her powers and to learn how to use them, let alone how to use them wisely. Instead of slowly and constantly  growing, her powers came to the surface almost all at once.

Oppressing her powers was the reason why it took so long until they developed to such an extent..
