After Lancelot stabbed Arthur, Merlin helped Arthur to escape from Camelot. No one has seen Arthur since then. When Arthur escaped, Guinevere was pregnant for three weeks but she didn't tell this to anyone.
She got married to Lancelot and he became the new king.Lancelot thought that he was the father of the baby but the father was Arthur.
2 years later...
I will take revenge on Lancelot. He will pay the price for trying to kill me.
Take care of my son Thomas and my wife Guinevere...
OMG! YOU ARE ALİVE. I THOUGHT YOU WERE DEAD. I COULDN'T HELP BUT MARRY LANCELOT. THOMAS IS YOUR SON NOT LANCELOT'S. I HAVE ALWAYS LOVED YOU.
How could you do this to me?! You got married to Lancelot and had a child, didn't you?
Arthur became the king of Camelot again and they lived happily ever after..
