Ghost Act 2

In act 2, Oswald confessed to Mrs. Alving that he has feelings for Regine, and also they found out that Engstrand is not Regine's father, instead Mr. Alving is. I was suprised when i found out these information after reading Act 2, and now im more interested in this play. I'm looking forward to find out more during the reading of Act 3. I love it so far.
