Tech help please - screening comments

[bluespirit]

I need to make a post in the Art Valentine comms & screen any comments left to them.
I know how to set the post so that comments are screened, but if I then reply to a screened comment, does it become visible to everyone?
If so, is there a way to avoid that happening please?

Sorry - never had to do this before (except once in the Art Santa & fudged that by just PMing the commenter! *g*)
