(S03E02) Someone want to tell me why they had to call this episode "The Glass Ballerina?" It referred to one tiny thing at the very beginning! I don't know, I guess I just like my episode titles to actually tell me what's going on and not give me some vague reference to something that's ultimately not all that important. Alias used to be notorious for this. But in the end, what did we learn from the glass ballerina? We learned that Sun is a big ol' cheating liar.
