That quick run to his arms and embrace has to be one of the best DS moments. I think, in a way, Barnabas does love her, but is (as of yet, or maybe just not realizing) not in love with her.
Although I wish they would just end the Barnabas/Maggie thing at this point (since Josette already made it clear to Barnabas - get over it and move on already, buster!), it did allow Angelique to have Maggie and Quentin see little hearts. For me, the Quentin/Maggie thing is one of the best couplings on the show. I can't wait until PT1970!
