I was really impressed with the bold choices made last night, exposing some pretty edgy topics in Deaf culture.
The new character Travis is first shown as a strong Deaf militant, intolerant of Hearing people, intolerant of Daphne's intermixing with Hearing and Deaf, and just bitter. Then the writers connected that behavior with another controversial topic: Deaf kids in Hearing families who don't learn sign.
I really like that this episode exposed two controversial topics to the masses, who may otherwise be ignorant of their very existence! Handwaves!!
