Like I've told you, I haven't made any decision yet. I will likely be sleeping on it to deliberate the matter anyway.
My question, and really this is closer to what I believe you should have done, is that you did explain the role earlier in the game. After that point, no further explanation was forthcoming. I believe that if you were not convinced that she understood the role, you ought to have explained it in other terms, or made sure that the current explanation suffices, rather than leaving it for a week and then picking it back up in LyLo. I accept your claim that your intent came from the thread and not anywhere else, but as a host, if you're going to ask players about their role understanding proactively, then you ought to be fully convinced that they do understand it, before leaving the conversation be and then coming back to it.
