The hands of this clock show 10:10, a time that looks almost balanced. What time does the clock appear to show in the mirror?

Balanced-looking is not the same as symmetric: the hour hand is a little PAST 10 while the minute hand is exactly on 2. In the mirror the minute hand points to 10 and the hour hand sits a little before 2, so the image reads $11:60-10:10=1:50$. 10:10 ignores where the hour hand sits, 2:50 forgets to borrow, and 8:20 is the water image.
