WZ is showing evidence that he's actually understanding what we're telling him, first of all he's now able to perform the 2 step process to store a spring loaded auto deploy light.

As you can see, mommy was especially delighted that WZ was able to handle the thing. Then there's this incident, where WZ is able to retrieve wat I ask him to!

I'm sure you can figure out why the toy is given such a name when you finish the video.
