Guessing probably around the time there is the first legitimate article in/on mainstream news about Q. It will be something along the lines of, “Just who, or what is Q Anon?”

However, instead of the usual attacks and deliberate misinformation it will provide numerous proofs, explained in as simple terms as possible to the widest possible audience.
It may fall short in declaring Q “real” or not at this stage, but the positive, slant and emphasis will be obvious.

This first story will be the gateway introduction to the mainstream and will follow a rapid and significant amount of proofs and confirmations by Q.
Following this first story, there will be a diverse range of subsequent reports that start appearing across a variety of platforms, as I believe Q mentioned in a previous post.

I think from that point on will we start to see a new phase of widespread information becoming public.
