The Pool of Tears - S1.E19

Oz, Eliot and Leo are trying to get Ada back to the school. Eliot continues to confront Oz about his willingness to sacrifice himself for others, asking him if he'd ever really saved anyone that way. Lotti releases her Chain, Leon, which looks like a large lion with a crown on it's head. When the Baskervilles catch Oz and the others a battle erupts. B. Rabbit appears and so does Jack Vessalius. Then it turns to Lotti's memorie of Jack Vessalius, over 100 years ago.
