i doubt youll find subs for season 2, it hasnt been released on dvd yet. search google for subtitles on season 1, there are many subs-webpages out there.
Are you Deaf? I'm Deaf as well. Alias Season 1 DVD Box have subtitles so, you can buy it. I always watch Alias with subtitles on TV. Next episode will be "Phrase One" in Australia where it will reveal which one going to die!
