Alias is getting better and back to its old form. They had a good old fashioned SD-6 mission with Dixon involved again. The danger is also back. The danger I refer to is the fact that all last season, Sidney's life as a double agent with SD-6 and the CIA provided a context of danger and tension. There was always the fear that SD-6 would sniff out her CIA missions. But this year they seemed to have made this extremely safe and relaxed, so she no longer seems worried about SD-6. However, with Jack Bristow (Sidney's double agent dad) under suspicion at SD-6, the danger and tension is back.

They need to do something with Derevko (Sidney's KGB mom) soon, or they'll lose momentum on that story line.
