>Anakin laments the fact that he just helped kill Mace. He's in turmoil over it. But a few seconds later he's pledging his allegance to Palpatine. Disgraceful writing. He should have agonized for much longer.

Palpatine was such a powerful user of the force he could disguise it from the entire Jedi Council even in their presence.

Once the council evaporated he could more directly manipulate Anakin. That was sort of the point of all that.
