It's great to see Roger again. I wish we had seen more of him.
When Nicholas arrived at Collinwood, he told Cassandra to get on with the job of re-cursing Barnabas. And now he has changed his mind and tells her to get rid of her obsession with re-cursing Barnabas. It's a good thing, however, that Cassandra didn't point out to Nicholas that he was as changeable as the wind, because he would have surely taken great pleasure in devising for her some punishment for sassing him.
And does Cassandra really think she'll be able to keep Nicholas from knowing that it was she who whacked Adam? Yes, of course she does, nitwit that she is.
We have finally arrived at the point where Nicholas starts corrupting Adam. And Adam was certainly ripe for the corrupting! I've done some thinking about the teaching of ethics to children since Adam was brought to life - although "thinking" may be the wrong word, because I did not have any useful thoughts. I guess the real problem is that there was so little time. When you raise a child (something I've never done), you have several years to teach him about right and wrong, and how to deal with various types of people, but with Adam there was a window of only a few weeks. And now Nicholas is closing that window.
The interaction between Nicholas and Carolyn was interesting. Although Nicholas had angered Carolyn, he then did her a favor, and came across as a perfect gentleman. It's the thin end of the wedge. Give Nicholas time, and he'll have Carolyn eating out of his hand and saying, "You're right, I don't need my soul...what do you think I could get for it on Ebay?"
