You ever do something then wonder what the impact of that was later? The closest example to what this comic is trying to portray is maybe how a teacher teaches kids and tries to set a good example to their class. They won't know the impact they make most likely as those students grow up and go their separate ways. But the teacher of course wants to hope they made a good impact.
Zephyr here has made some questionable choices, while not the best, they ended up being a good impact to Berry Punch and Cheerilee. Early on, we used to show Cheerilee and Berry Punch hanging out, but that sort of stopped for a few years.
As a recap, here are some moments related to the episode above.
