By the Seaside... or Not

Sweeney Todd had no desire to go to the sea with the excitable baker, whatsoever! In order to keep her quiet about the topic, he makes a deal with her to do just that once both Turpin and Bamford are truly dead. He didn't actually think that she would expect him to keep his word, how bloody wonderful. Mrs. Lovett expects him to fight back of course, but once they get to the sea, she finds out just how difficult it is to get him to go along with the plan. However, is his resistance only towards being there with her? Or is there something hiding behind his apparent hatred for the baker's dreams?
