5th Anniversary of Q will be 5th day of week 43(5), so "555". (43rd letter=Q=17=5)
So "35"
5:46 AM (29:46) on the clock.
+2 more days is "35 2"? (R's revenge?)
10/30 will be 5:48 AM on Qclock, so let's reverse 7:45 AM early predicted time of arrest and make it 5:47 AM (10/29 on Qclock) and let's make 8:30 AM late predicted time of arrest a percentage (83.0% of this year in the bag will be approx 22:32-hour on 10/30). OR 5:48 AM (10/30) is a reverse 8 4+5, 8:9 (9=21=3)… can make "8:30"
Might be a stretch, but it fits.
I like the "35" +2 angle, personally.
