It looks like it should be 
shell.get_player().props.player.add_tee(b)

So here it is again.

To get it from complaining about b and ser not being defined in deactivate I
added self.*. Is there a more correct way to do that?

Also what exactly does adding the elements do? How do I get the information
from them. Keep in mind this is my first time using Python.
