The only thing from The Titan's Curse I noticed in The Sea of Monsters so far is the manticore. They did the same thing with the Hydra in The Lightning Thief. In the film universe, monsters don't seem to be able to blend into the Mortal world the same way, as the Mist doesn't really seem to work all that well in the film universe (if the Mist exists at all). Because of this, I don't think the Manticore would have worked as a teacher at Bianca and Nico's school. They could just as easily have Thalia, Annabeth, and Percy get a message from Grover, and a monster happens to be attacking the same night, leading to Annabeth being captured and plot line restored.
