In it and of it?

I was sitting at the kitchen table with an open bottle of Aurora Black, about to fill three fountain pens. I called up to Elaine:

“Do you have any pens that need filled?”

I was not trying to be cute. I was using the [need + past participle] construction with an utter absence of self-consciousness. It just came out. I may now be not only in east-central Illinois but of it.

Then again, filling German fountain pens with Italian ink isn’t exactly a regionalism.
