Error when reflexive is last word

[sfillwo]

from multivalue import Dialects

aave = Dialects.AfricanAmericanVernacular()
output = aave.transform('Your brother probably does not want to tell you himself')

The code above produces the following error:

Traceback (most recent call last):
  File "/user/Documents/test.py", line 5, in <module>
    output = aave.transform('Your brother probably does not want to tell you himself')

    end_word = word_pos[span[1]]
IndexError: list index out of range

This seems to be coming from an issue when the reflexive (e.g. "himself") is the last word in the sentence, which causes an error due to a mismatch in the indexing.
