I confirm what Hmcooper4 said, and I even found the source :)

"Even though Cora (Barbara Hershey) says she killed Lancelot (Sinqua Walls), have we seen the last of him? Horowitz: No. Kitsis: Why does everyone just believe what Cora says? Not one person on the blogs have doubted Cora, as if she's the most trustworthy character that we have! She's not Snow White, for God's sake!"
