The end of its reply

Looking at this nonogram, I'll solve it step by step:

1. **Column 1: 5** → All cells filled. **Column 3: 0** → All cells empty.
2. **Row 5: 1 2** → (5,1)=# is the first run, gap at (5,3), then two adjacent: (5,4)=# and (5,5)=#.
3. **Column 4: 1** → Only (5,4) is filled, rest empty.
4. **Row 1: 1 1** → (1,1) is first; second must be (1,5) (since (1,4) is empty).
5. **Column 5: 1 1** → (1,5) and (5,5) work perfectly.
6. **Row 2: 2** → (2,1) is filled, so (2,2) must be filled (adjacent run of 2).
7. **Row 3: 2** → Same logic: (3,1) and (3,2) filled.
8. **Column 2: 2** → (2,2) and (3,2) form the run of 2. Rest empty.
9. **Row 4: 1** → Just (4,1). Everything else empty.
