S03:E20 - Legacy

Led by a dream, Veronica uses her mother's pendant as a guide to find her parents. She finds herself at the site of a stone monolith with strange carvings, and discovers that the pendant fits like a key into one of the etchings. A blast of energy surges from the stone, causing Veronica to recall new memories of her last day with her family. Meanwhile, an old enemy of Marguerite's returns to the plateau, armed with a mystical pendant that gives him new powers.
