Bastila: "You cannot win, Revan!"
I'm sure Revan was thinking somewhere along the line of, "Uh-huh, sure. I can waste you and the two fellow Jedi you have brought without breaking a sweat." And I believe he could have if Malek hadn't fire on his ship. In fact, Malek should have challenged Revan like a real Sith Apprentice would and face Revan in a lightsaber in which Revan would win. With Malek dead, he probably would have taken Bastila as his new apprentice.
