Zwei is like The Kid from "Blues Brothers 2000." He does so little that anyone else from the cast could very well do it in his place.

When you have a character that can be removed and have the means to keep the plot going, that character is completely unnecessary.

I love dogs, and Zwei is no exception. But his only purpose is to pander the audience.
