Before I forget, there is something I would like to mention. I do not consider speech a skill that is necessary to list. If you are capable of writing a convincing argument, then I think it should stand on its own, without the influence of a character stat. For anyone who has listed it, if you would like to replace it with something else, feel free. 

Anyway, I can see nothing wrong with Ilta. I just realized that I forgot to list alchemy under Sharee's skills, if that matters to you. I personally do not care if Ilta is also an alchemist, but I know some people don't like repeating roles.
