Pema Chödrön The book Bette is reading and cites to Tina is Comfortable with Uncertainty (2002) by Pema Chödrön. Born Deirdre Blomfield-Brown in 1936, in New York City, Pema Chödrön is a Buddhist nun. She currently teaches and resides in Gampo Abbey, a monastery in Nova Scotia. Tina remarks that Pema "looks like a Wookie". "Wookiee" is a race of hairy, extremely tall creatures in the Star Wars movies. It's possible that Tina (or the writers) made a mistake and actually meant to say that she looks like an "Ewok", a race of furry but small creatures first seen in the movie.
