When Eric Lang is going to do the experiment, he asks barnabas if he would like Jeff Clark's face, and Barnabas promptly agrees, simply for the fact that he thinks it will make Vicki fall in love with him just because he looks like Clark. To me that is so superficial! It just makes me want to shake Barnabas.
Also, during the experiment, the constant crackling of electricity from the machine drove me mad!
I know I've said this in previous posts, but Jerimiah's ghost returning to plague Barnabas and getting jealous because he thinks Barnabas took Josette away from him, when Jerimiah never even loved her in life. In death he should have realized what was going on. Why was he making such a ridiculous accusation?
