I don’t know how closely the OP is quoting the show in question, but I think we also have to be careful when addressing the two of these qualities. The Church (it seems to me) often makes a judgment about one while being silent about the other, and perhaps deliberately so.
For instance, another issue of licity that is often brought up is that in the Latin Rite, the bread intended for the Eucharist is to be made of wheaten flour and water. The addition of other ingredients renders it illicit – This is true whether the addition is a spoonful of honey, or enough milk, eggs, baking powder, vanilla et cetera to result in wedding cake. But (AFAIK) the Church does not address whether or how much an additive or additives affect the validity.
