Ooh, I kind of love this vein of predicting Dr. T's reasons for not wanting to listen to the voicemail. I'm going to say that there isn't any grand therapeutic reasoning but instead that he felt uncomfortable for reasons he doesn't quite understand and thus balked to avoid getting into whatever topic the voicemail would provoke. He put his own feelings first and LT feels understandably confused and rejected. If he had reasons, wouldn't he have shared them? Honesty is his strength, after all. Hesitating until 1) she felt ashamed for even bringing it up and then 2) dropped the subject doesn't seem like a very deft clinical maneuver. I can't imagine being allowed to "get away" with immediately dropping something I had clearly wanted to talk about a minute ago because broaching the topic suddenly became uncomfortable. My T would hop on that like a dog on a dropped steak.
