Well, since Anko was Orochimaru's student, one could assume she also has her Curse Seal at Level 2.
But when she sees Sasuke take control of the Seal, she is surprised and possibly even impressed, which could also mean she doesn't have the Curse Seal Level 2, or she was just too afraid to 'die', as the Four Sound had put it.
My question is, is it possible that Anko does have the ability to raise her Curse Seal up to Level 2?
Also, since she was Orochimaru's student, could she know how to summon the snakes (She does know Senei Yashu).. perhaps even Manda??
Lastly, what's the name of the move Kabuto uses as he camouflages himself when leading the Genins from Team 7 (Naruto, Sasuke, Sakura) in the Forest of Death?
