HBSMN:
"'I will not henceforth drink of this fruit of the vine' that He certainly drank the unfermented fruit of the vine prior to that Last Supper."

Your conclusion, that we know from these words "...that He certainly drank the unfermented fruit of the vine prior to that Last Supper", is inexplicable, not only because it is ambiguous, but relies on unwarrented preclusions. Jesus simply meant He longed to drink the Passover-'fruit of the vine' (whatever it would be). But He knew He would not because He would be sacrificed and would be dead when that would be drunk. He found hope and solace though in the fact He would rise again, and in the Kingdom thus erected, would drink with his disciples again in the last day of resurrection of the dead.
