Should grammar matter?

So I’m working on SWEET SALT AIR, rereading Chapter 6 for the umpteenth time, and I pause on the following paragraph:

“By Oliver Weeks?” Charlotte cut in.  “Still?  What a character.  Major interview there.”

Charlotte and Nicole are talking about ramekins that are hand-thrown by a ceramicist on Quinnipeague, but there is not one complete sentence in what Charlotte has said.  I try revising.

“Were those ramekins made by Oliver Weeks?” Charlotte cut in.  “Is he still here on Quinnipeague?  He is a total character.  An interview with him will be crucial to our book.”
