I have a potentially useless decode, but anyways, here it goes:
Normally, when Q writes "Nothing can stop what is coming", the nest sentence is "Nothing." with a .
However, not all sentences after are "Nothing" and some end with a !
The sequence so far is
… .!.!.!. .
This is the Q drops corresponding to each
2494 .
2513 .
2533 .
3312 ("Nothing" not in drop)
3320 .
3426 !
3498 .
3590 !
3784 .
3891 !
3897 .
4052 ("Nothing" not in drop)
4648 .
Therefore, I suspect that the next two drops containing "Nothing can stop what is coming" will contain a "Nothing" with a dot at the end. Maybe someone can see anything else here, I tried morse code, but it didn't work.
