Yes, especially since throughout the whole show the producers set it up to make the viewers think that there was going to be something between them eventually.
Yes I was upset, throughout the whole episode's I was under the impression that Jack and Sue would eventually fall in 사랑 and get together, that is what kept me watching because they made the best couple and the show 더 많이 interesting to watch, I kept waiting to see 더 많이 romance between them.
