If I had been asked to name this episode, I would have entitled it
'Distraction,' because all of the Fringe-related characters were quite distracted, with at least one thing apiece, in 302 except for Astrid, who seemed to be able to pretty much stay on task.
Walter was distracted by, of course, the strained post-reveal relationship he now finds himself in with Peter. Astrid told us Walter has not explained his side of the 'Peter' story to his surrogate son since they returned from 'Over There,' and she demanded he do so immediately, which was very Astrid. As if that wasn't enough distraction, Walter Bishop was distracted by the posthumous reading and revelation of his best friend, William Bell's will. It was quite telling that he did not respond to Peter's asking of what he received, but instead revealed the information instead (twice) to Astrid.
