I absolutely LOVED this epi. My favorite of the season, my all-time favorite since the S2 finally. The case was so interesting and heartbreaking/human. I was so happy to see Olivia and Peter work together again. Peter looks at Olivia so lovingly, and the best is that she saw it, so she's not "afraid" of him anymore.
There's so much more... Walter not being able to look at Peter, his comment on Peter being smart, Peter's badassness
Can't wait to see Peter help the Fringe team further.
Thank you Fringe for giving us amazing TV!!!!!
