Citizenship in the home

Rosemary decides to start moving her stuff into Dwight's house and they start talking about marriage. I could already see that Toby was not very happy about this situation. Toby has already shown what he thinks about Dwight and his mom. He's not happy that his mom is deciding to marry someone who shows no gratitude towards her own son. I wonder if Toby will talk to his mom about her desision and help her realize that Dwight is not the one for her and that she could do so much better than she's giving herself credit for.
