They didn't fully explain how Lancelot was temporarily resurrected. But my guess is that the Shade's body was fatally wounded, so Lancelot's life couldn't survive in the body for very long. It's like when you have been shot, you don't die until a couple of minutes. But in my theory, Merlin will free Morgana's soul when the Shade is 100% alive, therefore she won't die because she is in a fully healthy body. That's my view on it.
