This year KS kept saying 7. They didn't say anything about 8th, KS did say something about a partial season if it came to going past 7. May be that's what the asking Charlie about 8 is? Covering basis if it comes to a few more episodes past 7.
That was a great article and it lead me to this one, Donal Logue talks about Toric, the school shooting and this season (no spoilers):
