Pro Archia - please help.

[Rufus Coppertop]

I'm working through Pro Archia but the section italicized and underlined is driving me crazy.

ac ne quis a nobis hoc ita dici forte miretur quod alia quaedam in hoc facultas sit ingeni, neque haec dicendi ratio aut disciplina

quod - because
sit - he/it may be
facultas ingeni - abundance of talent
quaedam - a / a certain - it's feminine and nominative, so does it go with facultas?
alia - another / a different - it's ablative but because it's feminine, it can't go with in hoc.

I really don't know how to put this together in a way that makes sense.

[Nesrad]

alia is nom. and goes with quaedam and facultas:

"and lest anyone be amazed that I should say it this way, because there is some other skill of character..."

Of course alia is nominative! Why the blazes couldn't I see that?

Thank you Nesrad. In fact, gratias tibi do.
